VERIFY ADVISORY:
http://secunia.com/advisories/36136/

DESCRIPTION:
A security issue has been reported in the Linux Kernel, which can be
exploited by malicious, local users to disclose potentially sensitive
information.

The security issue is caused due to an error in the implementation of
the "sigaltstack()" function and can be exploited to disclose a
limited amount of kernel stack memory.

Successful exploitation may require that the kernel is running on a
64-bit platform.

SOLUTION:
Fixed in the GIT repository.

The vendor credits Ulrich Drepper.
