SUSE SLED12 / SLES12 Security Update : kernel (SUSE-SU-2015:1071-1)

This script is Copyright (C) 2015-2016 Tenable Network Security, Inc.

Synopsis :

The remote SUSE host is missing one or more security updates.

Description :

The SUSE Linux Enterprise 12 kernel was updated to version 3.12.43 to
receive various security and bugfixes.

Following security bugs were fixed :

- CVE-2014-3647: arch/x86/kvm/emulate.c in the KVM
subsystem in the Linux kernel through 3.17.2 did not
properly perform RIP changes, which allowed guest OS
users to cause a denial of service (guest OS crash) via
a crafted application (bsc#899192).

- CVE-2014-8086: Race condition in the
ext4_file_write_iter function in fs/ext4/file.c in the
Linux kernel through 3.17 allowed 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 (bsc#900881).

- CVE-2014-8159: The InfiniBand (IB) implementation did
not properly restrict use of User Verbs for registration
of memory regions, which allowed local users to access
arbitrary physical memory locations, and consequently
cause a denial of service (system crash) or gain
privileges, by leveraging permissions on a uverbs device
under /dev/infiniband/ (bsc#914742).

- CVE-2015-1465: The IPv4 implementation in the Linux
kernel before 3.18.8 did not properly consider the
length of the Read-Copy Update (RCU) grace period for
redirecting lookups in the absence of caching, which
allowed remote attackers to cause a denial of service
(memory consumption or system crash) via a flood of
packets (bsc#916225).

- CVE-2015-2041: net/llc/sysctl_net_llc.c in the Linux
kernel before 3.19 used an incorrect data type in a
sysctl table, which allowed local users to obtain
potentially sensitive information from kernel memory or
possibly have unspecified other impact by accessing a
sysctl entry (bsc#919007).

- CVE-2015-2042: net/rds/sysctl.c in the Linux kernel
before 3.19 used an incorrect data type in a sysctl
table, which allowed local users to obtain potentially
sensitive information from kernel memory or possibly
have unspecified other impact by accessing a sysctl
entry (bsc#919018).

- CVE-2015-2666: Fixed a flaw that allowed crafted
microcode to overflow the kernel stack (bsc#922944).

- CVE-2015-2830: Fixed int80 fork from 64-bit tasks
mishandling (bsc#926240).

- CVE-2015-2922: Fixed possible denial of service (DoS)
attack against IPv6 network stacks due to improper
handling of Router Advertisements (bsc#922583).

- CVE-2015-3331: Fixed buffer overruns in RFC4106
implementation using AESNI (bsc#927257).

- CVE-2015-3332: Fixed TCP Fast Open local DoS

- CVE-2015-3339: Fixed race condition flaw between the
chown() and execve() system calls which could have lead
to local privilege escalation (bsc#928130).

- CVE-2015-3636: Fixed use-after-free in ping sockets
which could have lead to local privilege escalation

The following non-security bugs were fixed :

- /proc/stat: convert to single_open_size() (bsc#928122).

unsigned (bsc#909312).

discard (bsc#927116).

- Btrfs: fix up bounds checking in lseek (bsc#927115).

- Fix rtworkqueues crash. Calling __sched_setscheduler()
in interrupt context is forbidden, and destroy_worker()
did so in the timer interrupt with a nohz_full config.
