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:
