Race condition in the ath_tx_aggr_sleep function in drivers/net/wireless/ath/ath9k/xmit.c in the Linux kernel before 3.13.7 allows remote attackers to cause a denial of service (system crash) via a large amount of network traffic that triggers certain list deletions.

According to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - In the Linux kernel, Hisilicon Network Subsystem (HNS)     does not consider the ETH_SS_PRIV_FLAGS case when     retrieving sset_count data. This allows local users to     cause a denial of service (buffer overflow and memory     corruption) or possibly have unspecified other     impacts.(CVE-2017-18222i1/4%0

  - A flaw was found in the way the Linux kernel's     networking implementation handled UDP packets with     incorrect checksum values. A remote attacker could     potentially use this flaw to trigger an infinite loop     in the kernel, resulting in a denial of service on the     system, or cause a denial of service in applications     using the edge triggered epoll     functionality.(CVE-2015-5366i1/4%0

  - A use-after-free vulnerability was found in the     kernel's socket recvmmsg subsystem. This may allow     remote attackers to corrupt memory and may allow     execution of arbitrary code. This corruption takes     place during the error handling routines within
    __sys_recvmmsg() function.(CVE-2016-7117i1/4%0

  - arch/x86/kvm/vmx.c in the Linux kernel through 4.6.3     mishandles the APICv on/off state, which allows guest     OS users to obtain direct APIC MSR access on the host     OS, and consequently cause a denial of service (host OS     crash) or possibly execute arbitrary code on the host     OS, via x2APIC mode.(CVE-2016-4440i1/4%0

  - In the Linux kernel before 4.17, a local attacker able     to set attributes on an xfs filesystem could make this     filesystem non-operational until the next mount by     triggering an unchecked error condition during an xfs     attribute change, because xfs_attr_shortform_addname in     fs/xfs/libxfs/xfs_attr.c mishandles ATTR_REPLACE     operations with conversion of an attr from short to     long form.(CVE-2018-18690i1/4%0

  - A flaw was found in the Linux kernel's ext4 filesystem.
    A local user can cause an out-of-bounds write and a     denial of service or unspecified other impact is     possible by mounting and operating a crafted ext4     filesystem image.(CVE-2018-10878i1/4%0

  - Xen 3.3.x through 4.5.x and the Linux kernel through     3.19.1 do not properly restrict access to PCI command     registers, which might allow local guest OS users to     cause a denial of service (non-maskable interrupt and     host crash) by disabling the (1) memory or (2) I/O     decoding for a PCI Express device and then accessing     the device, which triggers an Unsupported Request (UR)     response.(CVE-2015-2150i1/4%0

  - The assoc_array_insert_into_terminal_node() function in     'lib/assoc_array.c' in the Linux kernel before 4.5.3     does not check whether a slot is a leaf, which allows     local users to obtain sensitive information from kernel     memory or cause a denial of service (invalid pointer     dereference and out-of-bounds read) via an application     that uses associative-array data     structures.(CVE-2016-7914i1/4%0

  - It was found that the x86 ISA (Instruction Set     Architecture) is prone to a denial of service attack     inside a virtualized environment in the form of an     infinite loop in the microcode due to the way     (sequential) delivering of benign exceptions such as     #AC (alignment check exception) is handled. A     privileged user inside a guest could use this flaw to     create denial of service conditions on the host     kernel.(CVE-2015-5307i1/4%0

  - An issue was discovered in fs/f2fs/super.c in the Linux     kernel, which does not properly validate secs_per_zone     in a corrupted f2fs image. This may lead to a     divide-by-zero error and a system     crash.(CVE-2018-13100i1/4%0

  - The mISDN_sock_recvmsg function in     drivers/isdn/mISDN/socket.c in the Linux kernel before     3.12.4 does not ensure that a certain length value is     consistent with the size of an associated data     structure, which allows local users to obtain sensitive     information from kernel memory via a (1) recvfrom, (2)     recvmmsg, or (3) recvmsg system call.(CVE-2013-7266i1/4%0

  - A NULL pointer dereference flaw was found in the     rds_iw_laddr_check() function in the Linux kernel's     implementation of Reliable Datagram Sockets (RDS). A     local, unprivileged user could use this flaw to crash     the system.(CVE-2014-2678i1/4%0

  - A flaw was found in the Linux kernel's handling of     packets with the URG flag. Applications using the     splice() and tcp_splice_read() functionality could     allow a remote attacker to force the kernel to enter a     condition in which it could loop     indefinitely.(CVE-2017-6214i1/4%0

  - The kernel_wait4 function in kernel/exit.c in the Linux     kernel before 4.13, when an unspecified architecture     and compiler is used, might allow local users to cause     a denial of service by triggering an attempted use of     the -INT_MIN value.(CVE-2018-10087i1/4%0

  - Heap-based buffer overflow in the private wireless     extensions IOCTL implementation in wlan_hdd_wext.c in     the WLAN (aka Wi-Fi) driver for the Linux kernel 3.x     and 4.x, as used in Qualcomm Innovation Center (QuIC)     Android contributions for MSM devices and other     products, allows attackers to gain privileges via a     crafted application that establishes a packet     filter.(CVE-2015-0569i1/4%0

  - A race condition flaw was found in the Linux kernel's     ext4 file system implementation that allowed a local,     unprivileged user to crash the system by simultaneously     writing to a file and toggling the O_DIRECT flag using     fcntl(F_SETFL) on that file.(CVE-2014-8086i1/4%0

  - The mm_init function in kernel/fork.c in the Linux     kernel before 4.12.10 does not clear the -i1/4zexe_file     member of a new process's mm_struct, allowing a local     attacker to achieve a use-after-free condition and to     induce a kernel memory corruption on the system,     leading to a crash or possibly have unspecified other     impact by running a specially crafted program. Due to     the nature of the flaw, privilege escalation cannot be     fully ruled out, although we feel it is     unlikely.(CVE-2017-17052i1/4%0

  - A buffer overflow flaw was found in the way the Linux     kernel's Intel AES-NI instructions optimized version of     the RFC4106 GCM mode decryption functionality handled     fragmented packets. A remote attacker could use this     flaw to crash, or potentially escalate their privileges     on, a system over a connection with an active AES-GCM     mode IPSec security association.(CVE-2015-3331i1/4%0

  - A flaw was found in the processing of incoming L2CAP     bluetooth commands. Uninitialized stack variables can     be sent to an attacker leaking data in kernel address     space.(CVE-2017-1000410i1/4%0

  - It was found that a remote attacker could use a race     condition flaw in the ath_tx_aggr_sleep() function to     crash the system by creating large network traffic on     the system's Atheros 9k wireless network     adapter.(CVE-2014-2672i1/4%0

  - The yam_ioctl function in drivers/net/hamradio/yam.c in     the Linux kernel before 3.12.8 does not initialize a     certain structure member, which allows local users to     obtain sensitive information from kernel memory by     leveraging the CAP_NET_ADMIN capability for an     SIOCYAMGCFG ioctl call.(CVE-2014-1446)

  - The help function in net/netfilter/nf_nat_irc.c in the     Linux kernel before 3.12.8 allows remote attackers to     obtain sensitive information from kernel memory by     establishing an IRC DCC session in which incorrect     packet data is transmitted during use of the NAT mangle     feature.(CVE-2014-1690)

  - A flaw was found in the way the Linux kernel's floppy     driver handled user space provided data in certain     error code paths while processing FDRAWCMD IOCTL     commands. A local user with write access to /dev/fdX     could use this flaw to free (using the kfree()     function) arbitrary kernel memory. (CVE-2014-1737,     Important)

  - It was found that the Linux kernel's floppy driver     leaked internal kernel memory addresses to user space     during the processing of the FDRAWCMD IOCTL command. A     local user with write access to /dev/fdX could use this     flaw to obtain information about the kernel heap     arrangement. (CVE-2014-1738, Low)

  - Note: A local user with write access to /dev/fdX could     use these two flaws (CVE-2014-1737 in combination with     CVE-2014-1738) to escalate their privileges on the     system.(CVE-2014-1737)

  - The security_context_to_sid_core function in     security/selinux/ss/services.c in the Linux kernel     before 3.13.4 allows local users to cause a denial of     service (system crash) by leveraging the CAP_MAC_ADMIN     capability to set a zero-length security     context.(CVE-2014-1874)

  - The nfs_can_extend_write function in fs/nfs/write.c in     the Linux kernel before 3.13.3 relies on a write     delegation to extend a write operation without a     certain up-to-date verification, which allows local     users to obtain sensitive information from kernel     memory in opportunistic circumstances by writing to a     file in an NFS filesystem and then reading the same     file.(CVE-2014-2038)

  - The ip6_route_add function in net/ipv6/route.c in the     Linux kernel through 3.13.6 does not properly count the     addition of routes, which allows remote attackers to     cause a denial of service (memory consumption) via a     flood of ICMPv6 Router Advertisement     packets.(CVE-2014-2309)

  - net/netfilter/nf_conntrack_proto_dccp.c in the Linux     kernel through 3.13.6 uses a DCCP header pointer     incorrectly, which allows remote attackers to cause a     denial of service (system crash) or possibly execute     arbitrary code via a DCCP packet that triggers a call     to the (1) dccp_new, (2) dccp_packet, or (3) dccp_error     function.(CVE-2014-2523)

  - Use-after-free vulnerability in the nfqnl_zcopy     function in net/netfilter/nfnetlink_queue_core.c in the     Linux kernel through 3.13.6 allows attackers to obtain     sensitive information from kernel memory by leveraging     the absence of a certain orphaning operation. NOTE: the     affected code was moved to the skb_zerocopy function in     net/core/skbuff.c before the vulnerability was     announced.(CVE-2014-2568)

  - It was found that a remote attacker could use a race     condition flaw in the ath_tx_aggr_sleep() function to     crash the system by creating large network traffic on     the system's Atheros 9k wireless network     adapter.(CVE-2014-2672)

  - A flaw was found in the way the Linux kernel performed     forking inside of a transaction. A local, unprivileged     user on a PowerPC system that supports transactional     memory could use this flaw to crash the     system.(CVE-2014-2673)

  - A race condition flaw was found in the way the Linux     kernel's mac80211 subsystem implementation handled     synchronization between TX and STA wake-up code paths.
    A remote attacker could use this flaw to crash the     system.(CVE-2014-2706)

  - A use-after-free flaw was found in the way the     ping_init_sock() function of the Linux kernel handled     the group_info reference counter. A local, unprivileged     user could use this flaw to crash the system or,     potentially, escalate their privileges on the     system.(CVE-2014-2851)

  - It was found that the try_to_unmap_cluster() function     in the Linux kernel's Memory Managment subsystem did     not properly handle page locking in certain cases,     which could potentially trigger the BUG_ON() macro in     the mlock_vma_page() function.

  - The (1) BPF_S_ANC_NLATTR and (2) BPF_S_ANC_NLATTR_NEST     extension implementations in the sk_run_filter function     in net/core/filter.c in the Linux kernel through 3.14.3     do not check whether a certain length value is     sufficiently large, which allows local users to cause a     denial of service (integer underflow and system crash)     via crafted BPF instructions. NOTE: the affected code     was moved to the __skb_get_nlattr and
    __skb_get_nlattr_nest functions before the     vulnerability was announced.(CVE-2014-3144)

  - The BPF_S_ANC_NLATTR_NEST extension implementation in     the sk_run_filter function in net/core/filter.c in the     Linux kernel through 3.14.3 uses the reverse order in a     certain subtraction, which allows local users to cause     a denial of service (over-read and system crash) via     crafted BPF instructions. NOTE: the affected code was     moved to the __skb_get_nlattr_nest function before the     vulnerability was announced.(CVE-2014-3145)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2015-0290 advisory.

  - arch/x86/kvm/vmx.c in the KVM subsystem in the Linux kernel before 3.17.2 on Intel processors does not     ensure that the value in the CR4 control register remains the same after a VM entry, which allows host OS     users to kill arbitrary processes or cause a denial of service (system disruption) by leveraging /dev/kvm     access, as demonstrated by PR_SET_TSC prctl calls within a modified copy of QEMU. (CVE-2014-3690)

  - The Linux kernel through 3.14.5 does not properly consider the presence of hugetlb entries, which allows     local users to cause a denial of service (memory corruption or system crash) by accessing certain memory     locations, as demonstrated by triggering a race condition via numa_maps read operations during hugepage     migration, related to fs/proc/task_mmu.c and mm/mempolicy.c. (CVE-2014-3940)

  - kernel/trace/trace_syscalls.c in the Linux kernel through 3.17.2 does not properly handle private syscall     numbers during use of the perf subsystem, which allows local users to cause a denial of service (out-of-     bounds read and OOPS) or bypass the ASLR protection mechanism via a crafted application. (CVE-2014-7825)

  - kernel/trace/trace_syscalls.c in the Linux kernel through 3.17.2 does not properly handle private syscall     numbers during use of the ftrace subsystem, which allows local users to gain privileges or cause a denial     of service (invalid pointer dereference) via a crafted application. (CVE-2014-7826)

  - Race condition in the ext4_file_write_iter function in fs/ext4/file.c in the Linux kernel through 3.17     allows local users to cause a denial of service (file unavailability) via a combination of a write action     and an F_SETFL fcntl operation for the O_DIRECT flag. (CVE-2014-8086)

  - net/netfilter/nf_conntrack_proto_generic.c in the Linux kernel before 3.18 generates incorrect conntrack     entries during handling of certain iptables rule sets for the SCTP, DCCP, GRE, and UDP-Lite protocols,     which allows remote attackers to bypass intended access restrictions via packets with disallowed port     numbers. (CVE-2014-8160)

  - The filesystem implementation in the Linux kernel before 3.13 performs certain operations on lists of     files with an inappropriate locking approach, which allows local users to cause a denial of service (soft     lockup or system crash) via unspecified use of Asynchronous I/O (AIO) operations. (CVE-2014-8172)

  - The pmd_none_or_trans_huge_or_clear_bad function in include/asm-generic/pgtable.h in the Linux kernel     before 3.13 on NUMA systems does not properly determine whether a Page Middle Directory (PMD) entry is a     transparent huge-table entry, which allows local users to cause a denial of service (NULL pointer     dereference and system crash) or possibly have unspecified other impact via a crafted MADV_WILLNEED     madvise system call that leverages the absence of a page-table lock. (CVE-2014-8173)

  - The ieee80211_fragment function in net/mac80211/tx.c in the Linux kernel before 3.13.5 does not properly     maintain a certain tail pointer, which allows remote attackers to obtain sensitive cleartext information     by reading packets. (CVE-2014-8709)

  - Stack-based buffer overflow in the ttusbdecfe_dvbs_diseqc_send_master_cmd function in     drivers/media/usb/ttusb-dec/ttusbdecfe.c in the Linux kernel before 3.17.4 allows local users to cause a     denial of service (system crash) or possibly gain privileges via a large message length in an ioctl call.
    (CVE-2014-8884)

  - The XFS implementation in the Linux kernel before 3.15 improperly uses an old size value during remote     attribute replacement, which allows local users to cause a denial of service (transaction overrun and data     corruption) or possibly gain privileges by leveraging XFS filesystem access. (CVE-2015-0274)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 6.4 Extended Update Support.

Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

* A use-after-free flaw was found in the way the ping_init_sock() function of the Linux kernel handled the group_info reference counter.
A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-2851, Important)

* A NULL pointer dereference flaw was found in the rds_ib_laddr_check() function in the Linux kernel's implementation of Reliable Datagram Sockets (RDS). A local, unprivileged user could use this flaw to crash the system. (CVE-2013-7339, Moderate)

* It was found that a remote attacker could use a race condition flaw in the ath_tx_aggr_sleep() function to crash the system by creating large network traffic on the system's Atheros 9k wireless network adapter. (CVE-2014-2672, Moderate)

* A NULL pointer dereference flaw was found in the rds_iw_laddr_check() function in the Linux kernel's implementation of Reliable Datagram Sockets (RDS). A local, unprivileged user could use this flaw to crash the system. (CVE-2014-2678, Moderate)

* A race condition flaw was found in the way the Linux kernel's mac80211 subsystem implementation handled synchronization between TX and STA wake-up code paths. A remote attacker could use this flaw to crash the system. (CVE-2014-2706, Moderate)

This update also fixes the following bugs :

* The Completely Fair Scheduler (CFS) did not verify whether the CFS period timer is running while throttling tasks on the CFS run queue.
Therefore under certain circumstances, the CFS run queue became stuck because the CFS period timer was inactive and could not be restarted.
To fix this problem, the CFS now restarts the CFS period timer inside the throttling function if it is inactive. (BZ#1120666)

* A previous change to the SCSI code fixed a race condition that could occur when removing a SCSI device. However, that change caused performance degradation because it used a certain function from the block layer code that was returning different values compared with later versions of the kernel. This update alters the SCSI code to properly utilize the values returned by the block layer code.
(BZ#1117581)

* If a statically defined gateway became unreachable and its corresponding neighbor entry entered a FAILED state, the gateway stayed in the FAILED state even after it became reachable again. This prevented routing of the traffic through that gateway. This update allows probing such a gateway automatically and routing the traffic through the gateway again once it becomes reachable. (BZ#1115262)

* A miscalculation in the 'radix_tree' swap encoding corrupted swap area indexes bigger than 8 by truncating lower bits of swap entries.
Consequently, systems with more than 8 swap areas could trigger a bogus OOM scenario when swapping out to such a swap area. This update fixes this problem by reducing a return value of the SWP_TYPE_SHIFT() function and removing a broken function call from the read_swap_header() function. (BZ#1099727)

* The automatic route cache rebuilding feature could incorrectly compute the length of a route hash chain if the cache contained multiple entries with the same key but a different TOS, mark, or OIF bit. Consequently, the feature could reach the rebuild limit and disable the routing cache on the system. This problem is fixed by using a helper function that avoids counting such duplicate routes.
(BZ#1113823)

* When booting a guest in the Hyper-V environment and enough of Programmable Interval Timer (PIT) interrupts were lost or not injected into the guest on time, the kernel panicked and the guest failed to boot. This problem has been fixed by bypassing the relevant PIT check when the guest is running under the Hyper-V environment. (BZ#1112225)

All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 7.

The Red Hat Security Response Team has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

* It was found that Linux kernel's ptrace subsystem did not properly sanitize the address-space-control bits when the program-status word (PSW) was being set. On IBM S/390 systems, a local, unprivileged user could use this flaw to set address-space-control bits to the kernel space, and thus gain read and write access to kernel memory.
(CVE-2014-3534, Important)

* It was found that the permission checks performed by the Linux kernel when a netlink message was received were not sufficient. A local, unprivileged user could potentially bypass these restrictions by passing a netlink socket as stdout or stderr to a more privileged process and altering the output of this process. (CVE-2014-0181, Moderate)

* It was found that a remote attacker could use a race condition flaw in the ath_tx_aggr_sleep() function to crash the system by creating large network traffic on the system's Atheros 9k wireless network adapter. (CVE-2014-2672, Moderate)

* A flaw was found in the way the Linux kernel performed forking inside of a transaction. A local, unprivileged user on a PowerPC system that supports transactional memory could use this flaw to crash the system. (CVE-2014-2673, Moderate)

* A race condition flaw was found in the way the Linux kernel's mac80211 subsystem implementation handled synchronization between TX and STA wake-up code paths. A remote attacker could use this flaw to crash the system. (CVE-2014-2706, Moderate)

* An integer underflow flaw was found in the way the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation processed certain COOKIE_ECHO packets. By sending a specially crafted SCTP packet, a remote attacker could use this flaw to prevent legitimate connections to a particular SCTP server socket to be made.
(CVE-2014-4667, Moderate)

Red Hat would like to thank Martin Schwidefsky of IBM for reporting CVE-2014-3534, Andy Lutomirski for reporting CVE-2014-0181, and Gopal Reddy Kodudula of Nokia Siemens Networks for reporting CVE-2014-4667.

This update also fixes the following bugs :

* Due to a NULL pointer dereference bug in the IPIP and SIT tunneling code, a kernel panic could be triggered when using IPIP or SIT tunnels with IPsec. This update restructures the related code to avoid a NULL pointer dereference and the kernel no longer panics when using IPIP or SIT tunnels with IPsec. (BZ#1114957)

* Previously, an IBM POWER8 system could terminate unexpectedly when the kernel received an IRQ while handling a transactional memory re-checkpoint critical section. This update ensures that IRQs are disabled in this situation and the problem no longer occurs.
(BZ#1113150)

* A missing read memory barrier, rmb(), in the bnx2x driver caused the kernel to crash under various circumstances. This problem has been fixed by adding an rmb() call to the relevant place in the bnx2x code.
(BZ#1107721)

* The hpwdt driver previously emitted a panic message that was misleading on certain HP systems. This update ensures that upon a kernel panic, hpwdt displays information valid on all HP systems.
(BZ#1096961)

* The qla2xxx driver has been upgraded to version 8.06.00.08.07.0-k3, which provides a number of bug fixes over the previous version in order to correct various timeout problems with the mailbox commands.
(BZ#1112389)

* The SCSI mid-layer could retry an I/O operation indefinitely if a storage array repeatedly returned a CHECK CONDITION status to that I/O operation but the sense data was invalid. This update fixes the problem by limiting a time for which is such an I/O operation retried.
(BZ#1114468)

All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2014-1023 advisory.

  - Race condition in the ath_tx_aggr_sleep function in drivers/net/wireless/ath/ath9k/xmit.c in the Linux     kernel before 3.13.7 allows remote attackers to cause a denial of service (system crash) via a large     amount of network traffic that triggers certain list deletions. (CVE-2014-2672)

  - Race condition in the mac80211 subsystem in the Linux kernel before 3.13.7 allows remote attackers to     cause a denial of service (system crash) via network traffic that improperly interacts with the     WLAN_STA_PS_STA state (aka power-save mode), related to sta_info.c and tx.c. (CVE-2014-2706)

  - The Netlink implementation in the Linux kernel through 3.14.1 does not provide a mechanism for authorizing     socket operations based on the opener of a socket, which allows local users to bypass intended access     restrictions and modify network configurations by using a Netlink socket for the (1) stdout or (2) stderr     of a setuid program. (CVE-2014-0181)

  - The arch_dup_task_struct function in the Transactional Memory (TM) implementation in     arch/powerpc/kernel/process.c in the Linux kernel before 3.13.7 on the powerpc platform does not properly     interact with the clone and fork system calls, which allows local users to cause a denial of service     (Program Check and system crash) via certain instructions that are executed with the processor in the     Transactional state. (CVE-2014-2673)

  - arch/s390/kernel/ptrace.c in the Linux kernel before 3.15.8 on the s390 platform does not properly     restrict address-space control operations in PTRACE_POKEUSR_AREA requests, which allows local users to     obtain read and write access to kernel memory locations, and consequently gain privileges, via a crafted     application that makes a ptrace system call. (CVE-2014-3534)

  - The sctp_association_free function in net/sctp/associola.c in the Linux kernel before 3.15.2 does not     properly manage a certain backlog value, which allows remote attackers to cause a denial of service     (socket outage) via a crafted SCTP packet. (CVE-2014-4667)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Updated kernel packages that fix multiple security issues, several bugs, and add one enhancement are now available for Red Hat Enterprise Linux 6.

The remote Oracle Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2014-0981 advisory.

  - Integer overflow in the ping_init_sock function in net/ipv4/ping.c in the Linux kernel through 3.14.1     allows local users to cause a denial of service (use-after-free and system crash) or possibly gain     privileges via a crafted application that leverages an improperly managed reference counter.
    (CVE-2014-2851)

  - The rds_ib_laddr_check function in net/rds/ib.c in the Linux kernel before 3.12.8 allows local users to     cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other     impact via a bind system call for an RDS socket on a system that lacks RDS transports. (CVE-2013-7339)

  - The (1) BPF_S_ANC_NLATTR and (2) BPF_S_ANC_NLATTR_NEST extension implementations in the sk_run_filter     function in net/core/filter.c in the Linux kernel through 3.14.3 do not check whether a certain length     value is sufficiently large, which allows local users to cause a denial of service (integer underflow and     system crash) via crafted BPF instructions. NOTE: the affected code was moved to the __skb_get_nlattr and
    __skb_get_nlattr_nest functions before the vulnerability was announced. (CVE-2014-3144)

  - The BPF_S_ANC_NLATTR_NEST extension implementation in the sk_run_filter function in net/core/filter.c in     the Linux kernel through 3.14.3 uses the reverse order in a certain subtraction, which allows local users     to cause a denial of service (over-read and system crash) via crafted BPF instructions. NOTE: the affected     code was moved to the __skb_get_nlattr_nest function before the vulnerability was announced.
    (CVE-2014-3145)

  - The rds_iw_laddr_check function in net/rds/iw.c in the Linux kernel through 3.14 allows local users to     cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other     impact via a bind system call for an RDS socket on a system that lacks RDS transports. (CVE-2014-2678)

  - The futex_wait_requeue_pi function in kernel/futex.c in the Linux kernel before 3.5.1 does not ensure that     calls have two different futex addresses, which allows local users to cause a denial of service (NULL     pointer dereference and system crash) or possibly have unspecified other impact via a crafted     FUTEX_WAIT_REQUEUE_PI command. (CVE-2012-6647)

  - Race condition in the ath_tx_aggr_sleep function in drivers/net/wireless/ath/ath9k/xmit.c in the Linux     kernel before 3.13.7 allows remote attackers to cause a denial of service (system crash) via a large     amount of network traffic that triggers certain list deletions. (CVE-2014-2672)

Updated kernel-rt packages that fix multiple security issues are now available for Red Hat Enterprise MRG 2.5.

The Red Hat Security Response Team has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The kernel-rt packages contain the Linux kernel, the core of any Linux operating system.

  * A race condition leading to a use-after-free flaw was     found in the way the Linux kernel's TCP/IP protocol     suite implementation handled the addition of fragments     to the LRU (Last-Recently Used) list under certain     conditions. A remote attacker could use this flaw to     crash the system or, potentially, escalate their     privileges on the system by sending a large amount of     specially crafted fragmented packets to that system.
    (CVE-2014-0100, Important)

  * A race condition flaw, leading to heap-based buffer     overflows, was found in the way the Linux kernel's N_TTY     line discipline (LDISC) implementation handled     concurrent processing of echo output and TTY write     operations originating from user space when the     underlying TTY driver was PTY. An unprivileged, local     user could use this flaw to crash the system or,     potentially, escalate their privileges on the system.
    (CVE-2014-0196, Important)

  * A flaw was found in the way the Linux kernel's floppy     driver handled user space provided data in certain error     code paths while processing FDRAWCMD IOCTL commands. A     local user with write access to /dev/fdX could use this     flaw to free (using the kfree() function) arbitrary     kernel memory. (CVE-2014-1737, Important)

  * It was found that the Linux kernel's floppy driver     leaked internal kernel memory addresses to user space     during the processing of the FDRAWCMD IOCTL command. A     local user with write access to /dev/fdX could use this     flaw to obtain information about the kernel heap     arrangement. (CVE-2014-1738, Low)

Note: A local user with write access to /dev/fdX could use these two flaws (CVE-2014-1737 in combination with CVE-2014-1738) to escalate their privileges on the system.

  * A use-after-free flaw was found in the way the     ping_init_sock() function of the Linux kernel handled     the group_info reference counter. A local, unprivileged     user could use this flaw to crash the system or,     potentially, escalate their privileges on the system.
    (CVE-2014-2851, Important)

  * It was found that a remote attacker could use a race     condition flaw in the ath_tx_aggr_sleep() function to     crash the system by creating large network traffic on     the system's Atheros 9k wireless network adapter.
    (CVE-2014-2672, Moderate)

  * A NULL pointer dereference flaw was found in the     rds_iw_laddr_check() function in the Linux kernel's     implementation of Reliable Datagram Sockets (RDS). A     local, unprivileged user could use this flaw to crash     the system. (CVE-2014-2678, Moderate)

  * A race condition flaw was found in the way the Linux     kernel's mac80211 subsystem implementation handled     synchronization between TX and STA wake-up code paths.
    A remote attacker could use this flaw to crash the     system. (CVE-2014-2706, Moderate)

  * It was found that the try_to_unmap_cluster() function in     the Linux kernel's Memory Managment subsystem did not     properly handle page locking in certain cases, which     could potentially trigger the BUG_ON() macro in the     mlock_vma_page() function. A local, unprivileged user     could use this flaw to crash the system. (CVE-2014-3122,     Moderate)

Users are advised to upgrade to these updated packages, which upgrade the kernel-rt kernel to version kernel-rt-3.10.33-rt32.34 and correct these issues. The system must be rebooted for this update to take effect.

This update for the compat-wireless kernel modules provides many fixes and enhancements :

  - Fix potential crash problem in ath9k. (CVE-2014-2672,     bnc#871148)

  - Fix improper updates of MAC addresses in ath9k_htc.
    (bnc#851426, CVE-2013-4579)

  - Fix stability issues in iwlwifi. (bnc#865475)

  - Improve support for Intel 7625 cards in iwlwifi.
    (bnc#51021) Installation notes :

New driver modules may conflict with old modules, which are automatically loaded from the initrd file after reboot. To apply this maintenance update correctly, the following steps need to be executed on a SLEPOS system :

  - Rebuild image

  - Create specific scDistributionContainer with newly built     initrd and kernel

  - Put the updated system image in it as a scPosImage     object Alternatively, you can use a kernel parameter to     enforce using the kernel from the system image :

  - Rebuild image

  - Set the kernel parameter FORCE_KEXEC, by adding the     scPxeFileTemplate object under the relevant scPosImage     object, with the scKernelParameters attribute containing     'FORCE_KEXEC=yes'.

The Linux Kernel was updated to fix various security issues and bugs.

Main security issues fixed :

A security issue in the tty layer that was fixed that could be used by local attackers for code execution (CVE-2014-0196).

Two security issues in the floppy driver were fixed that could be used by local attackers on machines with the floppy to crash the kernel or potentially execute code in the kernel (CVE-2014-1737 CVE-2014-1738).

    -the-filesystem-end back as there is a better fix than     reverting the affecting patch.

  - Delete     patches.fixes/xfs-fix-xfs_buf_find-oops-on-blocks-beyond
    -the-filesystem-end. It turned out that this patch     causes regressions (bnc#858233) The upstream 3.7.x also     reverted it in the end (commit c3793e0d94af2).

  - tcp: syncookies: reduce cookie lifetime to 128 seconds     (bnc#833968).

  - tcp: syncookies: reduce mss table to four values     (bnc#833968).

Multiple vulnerabilities has been found and corrected in the Linux kernel :

kernel/auditsc.c in the Linux kernel through 3.14.5, when CONFIG_AUDITSYSCALL is enabled with certain syscall rules, allows local users to obtain potentially sensitive single-bit values from kernel memory or cause a denial of service (OOPS) via a large value of a syscall number (CVE-2014-3917).

The futex_requeue function in kernel/futex.c in the Linux kernel through 3.14.5 does not ensure that calls have two different futex addresses, which allows local users to gain privileges via a crafted FUTEX_REQUEUE command that facilitates unsafe waiter modification (CVE-2014-3153).

Race condition in the ath_tx_aggr_sleep function in drivers/net/wireless/ath/ath9k/xmit.c in the Linux kernel before 3.13.7 allows remote attackers to cause a denial of service (system crash) via a large amount of network traffic that triggers certain list deletions (CVE-2014-2672).

The (1) BPF_S_ANC_NLATTR and (2) BPF_S_ANC_NLATTR_NEST extension implementations in the sk_run_filter function in net/core/filter.c in the Linux kernel through 3.14.3 do not check whether a certain length value is sufficiently large, which allows local users to cause a denial of service (integer underflow and system crash) via crafted BPF instructions. NOTE: the affected code was moved to the
__skb_get_nlattr and __skb_get_nlattr_nest functions before the vulnerability was announced (CVE-2014-3144).

The BPF_S_ANC_NLATTR_NEST extension implementation in the sk_run_filter function in net/core/filter.c in the Linux kernel through 3.14.3 uses the reverse order in a certain subtraction, which allows local users to cause a denial of service (over-read and system crash) via crafted BPF instructions. NOTE: the affected code was moved to the __skb_get_nlattr_nest function before the vulnerability was announced (CVE-2014-3145).

Integer overflow in the ping_init_sock function in net/ipv4/ping.c in the Linux kernel through 3.14.1 allows local users to cause a denial of service (use-after-free and system crash) or possibly gain privileges via a crafted application that leverages an improperly managed reference counter (CVE-2014-2851).

The n_tty_write function in drivers/tty/n_tty.c in the Linux kernel through 3.14.3 does not properly manage tty driver access in the LECHO !OPOST case, which allows local users to cause a denial of service (memory corruption and system crash) or gain privileges by triggering a race condition involving read and write operations with long strings (CVE-2014-0196).

The raw_cmd_copyout function in drivers/block/floppy.c in the Linux kernel through 3.14.3 does not properly restrict access to certain pointers during processing of an FDRAWCMD ioctl call, which allows local users to obtain sensitive information from kernel heap memory by leveraging write access to a /dev/fd device (CVE-2014-1738).

The raw_cmd_copyin function in drivers/block/floppy.c in the Linux kernel through 3.14.3 does not properly handle error conditions during processing of an FDRAWCMD ioctl call, which allows local users to trigger kfree operations and gain privileges by leveraging write access to a /dev/fd device (CVE-2014-1737).

The rds_iw_laddr_check function in net/rds/iw.c in the Linux kernel through 3.14 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a bind system call for an RDS socket on a system that lacks RDS transports (CVE-2014-2678).

drivers/vhost/net.c in the Linux kernel before 3.13.10, when mergeable buffers are disabled, does not properly validate packet lengths, which allows guest OS users to cause a denial of service (memory corruption and host OS crash) or possibly gain privileges on the host OS via crafted packets, related to the handle_rx and get_rx_bufs functions (CVE-2014-0077).

The ip6_route_add function in net/ipv6/route.c in the Linux kernel through 3.13.6 does not properly count the addition of routes, which allows remote attackers to cause a denial of service (memory consumption) via a flood of ICMPv6 Router Advertisement packets (CVE-2014-2309).

Multiple array index errors in drivers/hid/hid-multitouch.c in the Human Interface Device (HID) subsystem in the Linux kernel through 3.11, when CONFIG_HID_MULTITOUCH is enabled, allow physically proximate attackers to cause a denial of service (heap memory corruption, or NULL pointer dereference and OOPS) via a crafted device (CVE-2013-2897).

net/netfilter/nf_conntrack_proto_dccp.c in the Linux kernel through 3.13.6 uses a DCCP header pointer incorrectly, which allows remote attackers to cause a denial of service (system crash) or possibly execute arbitrary code via a DCCP packet that triggers a call to the (1) dccp_new, (2) dccp_packet, or (3) dccp_error function (CVE-2014-2523).

Race condition in the mac80211 subsystem in the Linux kernel before 3.13.7 allows remote attackers to cause a denial of service (system crash) via network traffic that improperly interacts with the WLAN_STA_PS_STA state (aka power-save mode), related to sta_info.c and tx.c (CVE-2014-2706).

The sctp_sf_do_5_1D_ce function in net/sctp/sm_statefuns.c in the Linux kernel through 3.13.6 does not validate certain auth_enable and auth_capable fields before making an sctp_sf_authenticate call, which allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) via an SCTP handshake with a modified INIT chunk and a crafted AUTH chunk before a COOKIE_ECHO chunk (CVE-2014-0101).

The cifs_iovec_write function in fs/cifs/file.c in the Linux kernel through 3.13.5 does not properly handle uncached write operations that copy fewer than the requested number of bytes, which allows local users to obtain sensitive information from kernel memory, cause a denial of service (memory corruption and system crash), or possibly gain privileges via a writev system call with a crafted pointer (CVE-2014-0069).

arch/s390/kernel/head64.S in the Linux kernel before 3.13.5 on the s390 platform does not properly handle attempted use of the linkage stack, which allows local users to cause a denial of service (system crash) by executing a crafted instruction (CVE-2014-2039).

Buffer overflow in virt/kvm/irq_comm.c in the KVM subsystem in the Linux kernel before 3.2.24 allows local users to cause a denial of service (crash) and possibly execute arbitrary code via vectors related to Message Signaled Interrupts (MSI), irq routing entries, and an incorrect check by the setup_routing_entry function before invoking the kvm_set_irq function (CVE-2012-2137).

The security_context_to_sid_core function in security/selinux/ss/services.c in the Linux kernel before 3.13.4 allows local users to cause a denial of service (system crash) by leveraging the CAP_MAC_ADMIN capability to set a zero-length security context (CVE-2014-1874).

The updated packages provides a solution for these security issues.
