    Description:

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

    Following security bugs were fixed:
    - CVE-2015-7799: The slhc_init function in drivers/net/slip/slhc.c in the
    Linux kernel did not ensure that certain slot numbers were 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-2015-5283: The sctp_init function in net/sctp/protocol.c in the
    Linux kernel had an incorrect sequence of protocol-initialization steps,
    which allowed local users to cause a denial of service (panic or memory
    corruption) by creating SCTP sockets before all of the steps have
    finished (bnc#947155).
    - 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-2015-8104: The KVM subsystem in the Linux kernel allowed guest OS
    users to cause a denial of service (host OS panic or hang) by triggering
    many #DB (aka Debug) exceptions, related to svm.c (bnc#954404).
    - CVE-2015-5307: The KVM subsystem in the Linux kernel allowed guest OS
    users to cause a denial of service (host OS panic or hang) by triggering
    many #AC (aka Alignment Check) exceptions, related to svm.c and vmx.c
    (bnc#953527).
    - CVE-2015-7990: RDS: There was no verification that an underlying
    transport exists when creating a connection, causing usage of a NULL
    pointer (bsc#952384).
    - 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-2015-0272: Missing checks allowed remote attackers to cause a denial
    of service (IPv6 traffic disruption) via a crafted MTU value in an IPv6
    Router Advertisement (RA) message, a different vulnerability than
    CVE-2015-8215 (bnc#944296).
