(CVE-2014-5471,     CVE-2014-5472, Low)

This update also fixes the following bugs :

  - Previously, a kernel panic could occur if a process     reading from a locked NFS file was killed and the lock     was not released properly before the read operations     finished. Consequently, the system crashed. The code     handling file locks has been fixed, and instead of     halting, the system now emits a warning about the     unreleased lock.

  - A race condition in the command abort handling logic of     the ipr device driver could cause the kernel to panic     when the driver received a response to an abort command     prior to receiving other responses to the aborted     command due to the support for multiple interrupts. With     this update, the abort handler waits for the aborted     command's responses first before completing an abort     operation.

  - Previously, a race condition could occur when changing a     Page Table Entry (PTE) or a Page Middle Directory (PMD)     to 'pte_numa' or 'pmd_numa', respectively, causing the     kernel to crash. This update removes the BUG_ON() macro     from the __handle_mm_fault() function, preventing the     kernel panic in the aforementioned scenario.

The system must be rebooted for this update to take effect.

Nadav Amit reported that the KVM (Kernel Virtual Machine) mishandles noncanonical addresses when emulating instructions that change the rip (Instruction Pointer). A guest user with access to I/O or the MMIO can use this flaw to cause a denial of service (system crash) of the guest. (CVE-2014-3647)

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.

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 IPv6 DCCP implementation in the Linux kernel     mishandles inheritance, which allows local users to     cause a denial of service or possibly have unspecified     other impact via crafted system calls, a related issue     to CVE-2017-8890. An unprivileged local user could use     this flaw 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 we believe it is unlikely.(CVE-2017-9076i1/4%0

  - The Linux Kernel imposes a size restriction on the     arguments and environmental strings passed through     RLIMIT_STACK/RLIMIT_INFINITY, but does not take the     argument and environment pointers into account, which     allows attackers to bypass this     limitation.(CVE-2017-1000365i1/4%0

  - A buffer overflow flaw was found in the way the Linux     kernel's eCryptfs implementation decoded encrypted file     names. A local, unprivileged user could use this flaw     to crash the system or, potentially, escalate their     privileges on the system.(CVE-2014-9683i1/4%0

  - The Linux kernel was found vulnerable to an integer     overflow in the     drivers/video/fbdev/uvesafb.c:uvesafb_setcmap()     function. The vulnerability could result in local     attackers being able to crash the kernel or potentially     elevate privileges.(CVE-2018-13406i1/4%0

  - net/ceph/auth_x.c in Ceph, as used in the Linux kernel     before 3.16.3, does not properly validate auth replies,     which allows remote attackers to cause a denial of     service (system crash) or possibly have unspecified     other impact via crafted data from the IP address of a     Ceph Monitor.(CVE-2014-6418i1/4%0

  - A NULL pointer dereference flaw was found in the way     the Linux kernel's Common Internet File System (CIFS)     implementation handled mounting of file system shares.
    A remote attacker could use this flaw to crash a client     system that would mount a file system share from a     malicious server.(CVE-2014-7145i1/4%0

  - The udp6_ufo_fragment function in     net/ipv6/udp_offload.c in the Linux kernel through     3.12, when UDP Fragmentation Offload (UFO) is enabled,     does not properly perform a certain size comparison     before inserting a fragment header, which allows remote     attackers to cause a denial of service (panic) via a     large IPv6 UDP packet, as demonstrated by use of the     Token Bucket Filter (TBF) queueing     discipline.(CVE-2013-4563i1/4%0

  - The do_umount function in fs/namespace.c in the Linux     kernel through 3.17 does not require the CAP_SYS_ADMIN     capability for do_remount_sb calls that change the root     filesystem to read-only, which allows local users to     cause a denial of service (loss of writability) by     making certain unshare system calls, clearing the /     MNT_LOCKED flag, and making an MNT_FORCE umount system     call.(CVE-2014-7975i1/4%0

  - drivers/tty/n_tty.c in the Linux kernel before 4.14.11     allows local attackers (who are able to access pseudo     terminals) to hang/block further usage of any pseudo     terminal devices due to an EXTPROC versus ICANON     confusion in TIOCINQ.(CVE-2018-18386i1/4%0

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 Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-2395-1 advisory.

    Nadav Amit reported that the KVM (Kernel Virtual Machine) mishandles noncanonical addresses when emulating     instructions that change the rip (Instruction Pointer). A guest user with access to I/O or the MMIO can     use this flaw to cause a denial of service (system crash) of the guest. (CVE-2014-3647)

    A flaw was discovered with the handling of the invept instruction in the KVM (Kernel Virtual Machine)     subsystem of the Linux kernel. An unprivileged guest user could exploit this flaw to cause a denial of     service (system crash) on the guest. (CVE-2014-3646)

    Lars Bull reported a race condition in the PIT (programmable interrupt timer) emulation in the KVM (Kernel     Virtual Machine) subsystem of the Linux kernel. A local guest user with access to PIT i/o ports could     exploit this flaw to cause a denial of service (crash) on the host. (CVE-2014-3611)

    Lars Bull and Nadav Amit reported a flaw in how KVM (the Kernel Virtual Machine) handles noncanonical     writes to certain MSR registers. A privileged guest user can exploit this flaw to cause a denial of     service (kernel panic) on the host. (CVE-2014-3610)

    A bounds check error was discovered in the driver for the Logitech Unifying receivers and devices. A     physically proximate attacker could exploit this flaw to to cause a denial of service (invalid kfree) or     to execute arbitrary code. (CVE-2014-3182)

    Raphael Geissert reported a NULL pointer dereference in the Linux kernel's CIFS client. A remote CIFS     server could cause a denial of service (system crash) or possibly have other unspecified impact by     deleting IPC$ share during resolution of DFS referrals. (CVE-2014-7145)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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