An update that solves 7 vulnerabilities and has 54 fixes is
now available.

Description:

The SUSE Linux Enterprise 12 SP1 kernel was updated to 3.12.51 to receive
various security and bugfixes.

Following features were added:
– hwrng: Add a driver for the hwrng found in power7+ systems (fate#315784).

Following security bugs were fixed:
– CVE-2015-8215: net/ipv6/addrconf.c in the IPv6 stack in the Linux kernel
did not validate attempted changes to the MTU value, which allowed
context-dependent attackers to cause a denial of service (packet loss)
via a value that is (1) smaller than the minimum compliant value or (2)
larger than the MTU of an interface, as demonstrated by a Router
Advertisement (RA) message that is not validated by a daemon, a
different vulnerability than CVE-2015-0272. (bsc#955354)
– CVE-2015-5156: The virtnet_probe function in drivers/net/virtio_net.c in
the Linux kernel attempted to support a FRAGLIST feature without proper
memory allocation, which allowed guest OS users to cause a denial of
service (buffer overflow and memory corruption) via a crafted sequence
of fragmented packets (bnc#940776).
– CVE-2015-7872: The key_gc_unused_keys function in security/keys/gc.c in
the Linux kernel allowed local users to cause a denial of service (OOPS)
via crafted keyctl commands (bnc#951440).
– CVE-2015-7799: The slhc_init function in drivers/net/slip/slhc.c in the
Linux kernel did not ensure that certain slot numbers are valid, which
allowed local users to cause a denial of service (NULL pointer
dereference and system crash) via a crafted PPPIOCSMAXCID ioctl call
(bnc#949936).
– CVE-2015-2925: The prepend_path function in fs/dcache.c in the Linux
kernel did not properly handle rename actions inside a bind mount, which
allowed local users to bypass an intended container protection mechanism
by renaming a directory, related to a “double-chroot attack (bnc#926238).

creating a connection, preventing possible DoS (bsc#952384).
