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.

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 remote Oracle Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2014-3034 advisory.

  - The microcode on AMD 16h 00h through 0Fh processors does not properly handle the interaction between     locked instructions and write-combined memory types, which allows local users to cause a denial of service     (system hang) via a crafted application, aka the errata 793 issue. (CVE-2013-6885)

  - 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 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)

  - Buffer overflow in the complete_emulated_mmio function in arch/x86/kvm/x86.c in the Linux kernel before     3.13.6 allows guest OS users to execute arbitrary code on the host OS by leveraging a loop that triggers     an invalid memory copy affecting certain cancel_work_item data. (CVE-2014-0049)

  - The compat_sys_recvmmsg function in net/compat.c in the Linux kernel before 3.13.2, when CONFIG_X86_X32 is     enabled, allows local users to gain privileges via a recvmmsg system call with a crafted timeout pointer     parameter. (CVE-2014-0038)

  - Array index error in the kvm_vm_ioctl_create_vcpu function in virt/kvm/kvm_main.c in the KVM subsystem in     the Linux kernel through 3.12.5 allows local users to gain privileges via a large id value.
    (CVE-2013-4587)

  - 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-2013-7266)

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.

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.

* A flaw was found in the way the get_rx_bufs() function in the vhost_net implementation in the Linux kernel handled error conditions reported by the vhost_get_vq_desc() function. A privileged guest user could use this flaw to crash the host. (CVE-2014-0055, Important)

* A flaw was found in the way the Linux kernel processed an authenticated COOKIE_ECHO chunk during the initialization of an SCTP connection. A remote attacker could use this flaw to crash the system by initiating a specially crafted SCTP handshake in order to trigger a NULL pointer dereference on the system. (CVE-2014-0101, Important)

* A flaw was found in the way the Linux kernel's CIFS implementation handled uncached write operations with specially crafted iovec structures. An unprivileged local user with access to a CIFS share could use this flaw to crash the system, leak kernel memory, or, potentially, escalate their privileges on the system. Note: the default cache settings for CIFS mounts on Red Hat Enterprise Linux 6 prohibit a successful exploitation of this issue. (CVE-2014-0069, Moderate)

* A heap-based buffer overflow flaw was found in the Linux kernel's cdc-wdm driver, used for USB CDC WCM device management. An attacker with physical access to a system could use this flaw to cause a denial of service or, potentially, escalate their privileges. (CVE-2013-1860, Low)

Red Hat would like to thank Nokia Siemens Networks for reporting CVE-2014-0101, and Al Viro for reporting CVE-2014-0069.

This update also fixes several bugs. Documentation for these changes will be available shortly from the Technical Notes document linked to in the References section.

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 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2014-0328 advisory.

  - Heap-based buffer overflow in the wdm_in_callback function in drivers/usb/class/cdc-wdm.c in the Linux     kernel before 3.8.4 allows physically proximate attackers to cause a denial of service (system crash) or     possibly execute arbitrary code via a crafted cdc-wdm USB device. (CVE-2013-1860)

  - The get_rx_bufs function in drivers/vhost/net.c in the vhost-net subsystem in the Linux kernel package     before 2.6.32-431.11.2 on Red Hat Enterprise Linux (RHEL) 6 does not properly handle vhost_get_vq_desc     errors, which allows guest OS users to cause a denial of service (host OS crash) via unspecified vectors.
    (CVE-2014-0055)

  - 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)

  - 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)

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

    (CVE-2013-4587)

  - The KVM subsystem in the Linux kernel through 3.12.5     allows local users to gain privileges or cause a denial     of service (system crash) via a VAPIC synchronization     operation involving a page-end address. (bnc#853052).
    (CVE-2013-6368)

  - The apic_get_tmcct function in arch/x86/kvm/lapic.c in     the KVM subsystem in the Linux kernel through 3.12.5     allows guest OS users to cause a denial of service     (divide-by-zero error and host OS crash) via crafted     modifications of the TMICT value. (bnc#853051).
    (CVE-2013-6367)

  - Memory leak in the __kvm_set_memory_region function in     virt/kvm/kvm_main.c in the Linux kernel before 3.9     allows local users to cause a denial of service (memory     consumption) by leveraging certain device access to     trigger movement of memory slots. (bnc#851101).
    (CVE-2013-4592)

  - The lbs_debugfs_write function in     drivers/net/wireless/libertas/debugfs.c in the Linux     kernel through 3.12.1 allows local users to cause a     denial of service (OOPS) by leveraging root privileges     for a zero-length write operation. (bnc#852559).
    (CVE-2013-6378)

  - Multiple buffer overflows in     drivers/staging/wlags49_h2/wl_priv.c in the Linux kernel     before 3.12 allow local users to cause a denial of     service or possibly have unspecified other impact by     leveraging the CAP_NET_ADMIN capability and providing a     long station-name string, related to the (1)     wvlan_uil_put_info and (2) wvlan_set_station_nickname     functions. (bnc#849029). (CVE-2013-4514)

  - The bcm_char_ioctl function in     drivers/staging/bcm/Bcmchar.c in the Linux kernel before     3.12 does not initialize a certain data structure, which     allows local users to obtain sensitive information from     kernel memory via an IOCTL_BCM_GET_DEVICE_DRIVER_INFO     ioctl call. (bnc#849034). (CVE-2013-4515)

  - The ieee80211_radiotap_iterator_init function in     net/wireless/radiotap.c in the Linux kernel before     3.11.7 does not check whether a frame contains any data     outside of the header, which might allow attackers to     cause a denial of service (buffer over-read) via a     crafted header. (bnc#854634). (CVE-2013-7027)

  - The ipc_rcu_putref function in ipc/util.c in the Linux     kernel before 3.10 does not properly manage a reference     count, which allows local users to cause a denial of     service (memory consumption or system crash) via a     crafted application. (bnc#848321). (CVE-2013-4483)

  - Multiple integer overflows in Alchemy LCD frame-buffer     drivers in the Linux kernel before 3.12 allow local     users to create a read-write memory mapping for the     entirety of kernel memory, and consequently gain     privileges, via crafted mmap operations, related to the     (1) au1100fb_fb_mmap function in     drivers/video/au1100fb.c and the (2) au1200fb_fb_mmap     function in drivers/video/au1200fb.c.

It could occur while     doing recvmsg(2), recvfrom(2) socket calls. It occurs     due to improperly initialised msg_name &amp; msg_namelen     message header parameters. (bnc#854722). (CVE-2013-6463)

  - The aac_compat_ioctl function in     drivers/scsi/aacraid/linit.c in the Linux kernel before     3.11.8 does not require the CAP_SYS_RAWIO capability,     which allows local users to bypass intended access     restrictions via a crafted ioctl call. (bnc#852558).
    (CVE-2013-6383)

  - Off-by-one error in the get_prng_bytes function in     crypto/ansi_cprng.c in the Linux kernel through 3.11.4     makes it easier for context-dependent attackers to     defeat cryptographic protection mechanisms via multiple     requests for small amounts of data, leading to improper     management of the state of the consumed data.

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

The KVM subsystem in the Linux kernel through 3.12.5 allows local users to gain privileges or cause a denial of service (system crash) via a VAPIC synchronization operation involving a page-end address (CVE-2013-6368).

The apic_get_tmcct function in arch/x86/kvm/lapic.c in the KVM subsystem in the Linux kernel through 3.12.5 allows guest OS users to cause a denial of service (divide-by-zero error and host OS crash) via crafted modifications of the TMICT value (CVE-2013-6367).

Multiple buffer underflows in the XFS implementation in the Linux kernel through 3.12.1 allow local users to cause a denial of service (memory corruption) or possibly have unspecified other impact by leveraging the CAP_SYS_ADMIN capability for a (1) XFS_IOC_ATTRLIST_BY_HANDLE or (2) XFS_IOC_ATTRLIST_BY_HANDLE_32 ioctl call with a crafted length value, related to the xfs_attrlist_by_handle function in fs/xfs/xfs_ioctl.c and the xfs_compat_attrlist_by_handle function in fs/xfs/xfs_ioctl32.c (CVE-2013-6382).

Array index error in the kvm_vm_ioctl_create_vcpu function in virt/kvm/kvm_main.c in the KVM subsystem in the Linux kernel through 3.12.5 allows local users to gain privileges via a large id value (CVE-2013-4587).

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-2013-7266).

The atalk_recvmsg function in net/appletalk/ddp.c in the Linux kernel before 3.12.4 updates a certain length value without ensuring that an associated data structure has been initialized, which allows local users to obtain sensitive information from kernel memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call (CVE-2013-7267).
