    An update that solves 10 vulnerabilities and has 57 fixes is now available.

    Description:

    The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various
    security and bugfixes.

    Following security bugs were fixed:
    - CVE-2015-7509: Mounting ext4 filesystems in no-journal mode could hav
    lead to a system crash (bsc#956709).
    - 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-2015-8104: 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-2015-5157: arch/x86/entry/entry_64.S in the Linux kernel on the
    x86_64 platform mishandled IRET faults in processing NMIs that occurred
    during userspace execution, which might have allowed local users to gain
    privileges by triggering an NMI (bnc#938706).
    - 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).
    - CVE-2015-6937: The __rds_conn_create function in net/rds/connection.c in
    the Linux kernel allowed local users to cause a denial of service (NULL
    pointer dereference and system crash) or possibly have unspecified other
    impact by using a socket that was not properly bound (bnc#945825).
