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.

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 :

  - The kernel package contains the Linux kernel (vmlinuz),     the core of any Linux operating system. The kernel     handles the basic functions of the operating system:
    memory allocation, process allocation, device input and     output, etc.Security Fix(es):The walk_hugetlb_range()     function in 'mm/pagewalk.c' file in the Linux kernel     from v4.0-rc1 through v4.15-rc1 mishandles holes in     hugetlb ranges. This allows local users to obtain     sensitive information from uninitialized kernel memory     via crafted use of the mincore() system     call.(CVE-2017-16994)In the Linux kernel before 4.7,     the amd_gpio_remove function in     drivers/pinctrl/pinctrl-amd.c calls the     pinctrl_unregister function, leading to a double     free.(CVE-2017-18174)In the Linux kernel through     4.20.11, af_alg_release() in crypto/af_alg.c neglects     to set a NULL value for a certain structure member,     which leads to a use-after-free in     sockfs_setattr.(CVE-2019-8912)A security flaw was found     in the Linux kernel that an attempt to move page mapped     by AIO ring buffer to the other node triggers NULL     pointer dereference at trace_writeback_dirty_page(),     because aio_fs_backing_dev_info.dev is     0.(CVE-2016-3070)The NFSv4 implementation in the Linux     kernel through 4.11.1 allows local users to cause a     denial of service (resource consumption) by leveraging     improper channel callback shutdown when unmounting an     NFSv4 filesystem, aka a 'module reference and kernel     daemon' leak.(CVE-2017-9059)When creating audit records     for parameters to executed children processes, an     attacker can convince the Linux kernel audit subsystem     can create corrupt records which may allow an attacker     to misrepresent or evade logging of executing     commands.(CVE-2016-6136)A use-after-free vulnerability     was found in a network namespaces code affecting the     Linux kernel since v4.0-rc1 through v4.15-rc5. The     function get_net_ns_by_id() does not check for the     net::count value after it has found a peer network in     netns_ids idr which could lead to double free and     memory corruption. This vulnerability could allow an     unprivileged local user to induce kernel memory     corruption on the system, leading to a crash. Due to     the nature of the flaw, privilege escalation cannot be     fully ruled out, although it is thought to be     unlikely.(CVE-2017-15129)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)A flaw was     found in the Linux kernel key management subsystem in     which a local attacker could crash the kernel or     corrupt the stack and additional memory (denial of     service) by supplying a specially crafted RSA key. This     flaw panics the machine during the verification of the     RSA key.(CVE-2016-8650)The uio_mmap_physical function     in drivers/uio/uio.c in the Linux kernel before 3.12     does not validate the size of a memory block, which     allows local users to cause a denial of service (memory     corruption) or possibly gain privileges via crafted     mmap operations, a different vulnerability than     CVE-2013-4511.(CVE-2013-6763)In the Linux kernel before     4.20.5, attackers can trigger a     drivers/char/ipmi/ipmi_msghandler.c use-after-free and     OOPS by arranging for certain simultaneous execution of     the code, as demonstrated by a 'service ipmievd     restart' loop.(CVE-2019-9003)An integer overflow flaw     was found in the way the Linux kernel randomized the     stack for processes on certain 64-bit architecture     systems, such as x86-64, causing the stack entropy to     be reduced by four.(CVE-2015-1593)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)The kill_something_info     function in kernel/signal.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 via an INT_MIN     argument.(CVE-2018-10124)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)A flaw was found in the     Linux kernel in that the aoedisk_debugfs_show()     function in drivers/block/aoe/aoeblk.c allows local     users to obtain some kernel address information by     reading a debugfs file. This address is not useful to     commit a further attack.(CVE-2018-7754)ALSA sequencer     core initializes the event pool on demand by invoking     snd_seq_pool_init() when the first write happens and     the pool is empty. A user can reset the pool size     manually via ioctl concurrently, and this may lead to     UAF or out-of-bound access.(CVE-2018-7566)In the     function wmi_set_ie(), the length validation code does     not handle unsigned integer overflow properly. As a     result, a large value of the 'ie_len' argument can     cause a buffer overflow in all Android releases from     CAF (Android for MSM, Firefox OS for MSM, QRD Android)     using the Linux Kernel.(CVE-2018-5848)The Linux kernel     does not properly initialize memory in messages passed     between virtual guests and the host operating system in     the vhost/vhost.c:vhost_new_msg() function. This can     allow local privileged users to read some kernel memory     contents when reading from the /dev/vhost-net device     file.(CVE-2018-1118)Systems with microprocessors     utilizing speculative execution and speculative     execution of memory reads before the addresses of all     prior memory writes are known may allow unauthorized     disclosure of information to an attacker with local     user access via a side-channel analysis, aka     Speculative Store Bypass (SSB), Variant     4.(CVE-2018-3639)

  - The packet_recvmsg function in net/packet/af_packet.c     in the Linux kernel before 3.12.4 updates a certain     length value before 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-2013-7270)

  - The x25_recvmsg function in net/x25/af_x25.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-2013-7271)

  - The dgram_recvmsg function in net/ieee802154/dgram.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 stack     memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg     system call.(CVE-2013-7281)

  - 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)

  - A flaw was found in the way the Linux kernel's Crypto     subsystem handled automatic loading of kernel modules.
    A local user could use this flaw to load any installed     kernel module, and thus increase the attack surface of     the running kernel.(CVE-2013-7421)

  - A flaw was found in the Linux kernel's implementation     of Unix sockets. A server polling for client-socket     data could put the peer socket on a wait list the peer     socket could then close the connection, making the     reference on the wait list no longer valid. This could     lead to bypassing the permissions on a Unix socket and     packets being injected into the stream, and could also     panic the machine (denial of service).(CVE-2013-7446)

  - 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)

  - 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 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)

  - 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)

  - Race condition in the inet_frag_intern function in     net/ipv4/inet_fragment.c in the Linux kernel through     3.13.6 allows remote attackers to cause a denial of     service (use-after-free error) or possibly have     unspecified other impact via a large series of     fragmented ICMP Echo Request packets to a system with a     heavy CPU load.(CVE-2014-0100)

  - A flaw was found in the way the Linux kernel processed     an authenticated COOKIE_ECHO chunk during the     initialization of an SCTP connection.

  - The keyring_detect_cycle_iterator function in     security/keys/keyring.c in the Linux kernel through     3.13.6 does not properly determine whether keyrings are     identical, which allows local users to cause a denial     of service (OOPS) via crafted keyctl     commands.(CVE-2014-0102)

  - Use-after-free vulnerability in the skb_segment     function in net/core/skbuff.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.(CVE-2014-0131)

  - The ioapic_deliver function in virt/kvm/ioapic.c in the     Linux kernel through 3.14.1 does not properly validate     the kvm_irq_delivery_to_apic return value, which allows     guest OS users to cause a denial of service (host OS     crash) via a crafted entry in the redirection table of     an I/O APIC. NOTE: the affected code was moved to the     ioapic_service function before the vulnerability was     announced.(CVE-2014-0155)

  - 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)

The SUSE Linux Enterprise 12 kernel was updated to 3.12.61 to receive various security and bugfixes. The following security bugs were fixed :

  - CVE-2017-16939: The XFRM dump policy implementation in     net/xfrm/xfrm_user.c in the Linux kernel allowed local     users to gain privileges or cause a denial of service     (use-after-free) via a crafted SO_RCVBUF setsockopt     system call in conjunction with XFRM_MSG_GETPOLICY     Netlink messages (bnc#1069702 1069708).

  - CVE-2017-1000405: The Linux Kernel had a problematic use     of pmd_mkdirty() in the touch_pmd() function inside the     THP implementation. touch_pmd() could be reached by     get_user_pages(). In such case, the pmd would become     dirty. This scenario breaks the new     can_follow_write_pmd()'s logic - pmd could become dirty     without going through a COW cycle. This bug was not as     severe as the original 'Dirty cow' because an ext4 file     (or any other regular file) could not be mapped using     THP. Nevertheless, it did allow us to overwrite     read-only huge pages. For example, the zero huge page     and sealed shmem files could be overwritten (since their     mapping could be populated using THP). Note that after     the first write page-fault to the zero page, it will be     replaced with a new fresh (and zeroed) thp (bnc#1069496     1070307).

  - CVE-2017-16531: drivers/usb/core/config.c in the Linux     kernel allowed local users to cause a denial of service     (out-of-bounds read and system crash) or possibly have     unspecified other impact via a crafted USB device,     related to the USB_DT_INTERFACE_ASSOCIATION descriptor     (bnc#1066671).

  - CVE-2017-12193: The     assoc_array_insert_into_terminal_node function in     lib/assoc_array.c in the Linux kernel mishandled node     splitting, which allowed local users to cause a denial     of service (NULL pointer dereference and panic) via a     crafted application, as demonstrated by the keyring key     type, and key addition and link creation operations     (bnc#1066192).

  - CVE-2017-16529: The snd_usb_create_streams function in     sound/usb/card.c in the Linux kernel allowed local users     to cause a denial of service (out-of-bounds read and     system crash) or possibly have unspecified other impact     via a crafted USB device (bnc#1066650).

  - CVE-2017-16525: The usb_serial_console_disconnect     function in drivers/usb/serial/console.c in the Linux     kernel allowed local users to cause a denial of service     (use-after-free and system crash) or possibly have     unspecified other impact via a crafted USB device,     related to disconnection and failed setup (bnc#1066618).

  - CVE-2017-16537: The imon_probe function in     drivers/media/rc/imon.c in the Linux kernel allowed     local users to cause a denial of service (NULL pointer     dereference and system crash) or possibly have     unspecified other impact via a crafted USB device     (bnc#1066573).

  - CVE-2017-16536: The cx231xx_usb_probe function in     drivers/media/usb/cx231xx/cx231xx-cards.c in the Linux     kernel allowed local users to cause a denial of service     (NULL pointer dereference and system crash) or possibly     have unspecified other impact via a crafted USB device     (bnc#1066606).

  - CVE-2017-16527: sound/usb/mixer.c in the Linux kernel     allowed local users to cause a denial of service     (snd_usb_mixer_interrupt use-after-free and system     crash) or possibly have unspecified other impact via a     crafted USB device (bnc#1066625).

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.

New kernel packages are available for Slackware 14.1 (64-bit) to fix a security issue.

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

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).

The restore_fpu_checking function in arch/x86/include/asm/fpu-internal.h in the Linux kernel before 3.12.8 on the AMD K7 and K8 platforms does not clear pending exceptions before proceeding to an EMMS instruction, which allows local users to cause a denial of service (task kill) or possibly gain privileges via a crafted application (CVE-2014-1438).

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 updated packages provides a solution for these security issues.

Pageexec reported a bug in the Linux kernel's recvmsg syscall when called from code using the x32 ABI. An unprivileged local user could exploit this flaw to cause a denial of service (system crash) or gain administrator privileges.

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