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


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
– 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
– 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).
