DESCRIPTION:
A vulnerability has been discovered in the Linux Kernel, which can be
exploited by malicious, local users to gain escalated privileges.

The vulnerability is caused due to the kernel not properly
restricting access to "/proc/<pid>/mem" file, which can be exploited
to gain escalated privileges by e.g. writing into the memory of a
privileged process.

SOLUTION:
Fixed in the GIT repository.
