SUSE-SU-2016:0354-1

The SUSE Linux Enterprise 11 SP3 Realtime kernel was updated to receive various security and bugfixes.

Following security bugs were fixed: - 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: Verify the underlying transport exists before creating a connection, preventing possible DoS (bsc#952384, CVE-2015-7990). - CVE-2015-5157: arch/x86/entry/entry64.S in the Linux kernel on the x8664 platform mishandled IRET faults in processing NMIs that occurred during userspace execution, which might allow local users to gain privileges by triggering an NMI (bnc#937969 bnc#937970 bnc#938706 bnc#939207). - CVE-2015-7872: The keygcunusedkeys 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-2015-8215: 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. NOTE: the scope of CVE-2015-0272 is limited to the NetworkManager product. (bnc#955354). - CVE-2015-6937: The _rdsconncreate 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). - CVE-2015-6252: The vhostdevioctl function in drivers/vhost/vhost.c in the Linux kernel allowed local users to cause a denial of service (memory consumption) via a VHOSTSETLOG_FD ioctl call that triggers permanent file-descriptor allocation (bnc#942367).
