   An update that fixes three vulnerabilities is now
   available. It includes two new package versions.

Description:

   The SUSE Linux Enterprise 11 Service Pack 2 LTSS kernel has been updated
   to fix security issues on kernels on the x86_64 architecture.

   The following security bugs have been fixed:

       *

         CVE-2014-9322: A local privilege escalation in the x86_64 32bit
   compatibility signal handling was fixed, which could have been used by
   local attackers to crash the machine or execute code.

       *

         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.

       *

         CVE-2014-8133: Insufficient validation of TLS register usage could
   have leaked information from the kernel stack to userspace.

   Security Issues:

       * CVE-2014-8133
         <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-8133>
       * CVE-2014-9090
         <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-9090>
       * CVE-2014-9322
         <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-9322>
