  script_tag(name:"insight", value:"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).
- CVE-2015-7990: RDS: Verify the underlying transport exists before
 creating a connection, preventing possible DoS (bsc#952384).
The following non-security bugs were fixed:
- af_iucv: avoid path quiesce of severed path in shutdown() (bnc#954986,
 LTC#131684).
- alsa: hda - Disable 64bit address for Creative HDA controllers
 (bnc#814440).
- alsa: hda - Fix noise problems on Thinkpad T440s (boo#958504).
- alsa: hda - Fix noise problems on Thinkpad T440s (boo#958504).
- apparmor: allow SYS_CAP_RESOURCE to be sufficient to prlimit another
 task (bsc#921949).
- audit: correctly record file names with different path name types
 (bsc#950013).
- audit: create private file name copies when auditing inodes (bsc#950013).
- bcache: Add btree_insert_node() (bnc#951638).
- bcache: Add explicit keylist arg to btree_insert() (bnc#951638).
- bcache: backing device set to clean after finishing detach (bsc#951638).
- bcache: backing device set to clean after finishing detach (bsc#951638).
- bcache: Clean up keylist code (bnc#951638).
- bcache: Convert btree_insert_check_key() to ... [Please see the references for more information on the vulnerabilities]");
