The following security bugs have been fixed:

   * CVE-2015-2041: A information leak in the llc2_timeout_table was
     fixed (bnc#919007).
   * CVE-2014-9322: arch/x86/kernel/entry_64.S in the Linux kernel did
     not properly handle faults associated with the Stack Segment (SS)
     segment register, which allowed local users to gain privileges by
     triggering an IRET instruction that leads to access to a GS Base
     address from the wrong space (bnc#910251).
   * CVE-2014-9090: The do_double_fault function in
     arch/x86/kernel/traps.c in the Linux kernel did not properly handle
     faults associated with the Stack Segment (SS) segment register,
     which allowed local users to cause a denial of service (panic) via a
     modify_ldt system call, as demonstrated by sigreturn_32 in the
     1-clock-tests test suite (bnc#907818).
   * CVE-2014-4667: The sctp_association_free function in
     net/sctp/associola.c in the Linux kernel did not properly manage a
     certain backlog value, which allowed remote attackers to cause a
     denial of service (socket outage) via a crafted SCTP packet
     (bnc#885422).
   * CVE-2014-3673: The SCTP implementation in the Linux kernel allowed
