DESCRIPTION:
Ben Hawkes has reported some vulnerabilities in the Linux Kernel,
which can be exploited by malicious, local users to gain escalated
privileges.

1) Certain callers of the "compat_alloc_user_space()" function (e.g.
the "compat_mc_getsockopt()" function in net/compat.c) do not perform
any verification of the returned memory area, which can be exploited
to cause a kernel memory corruption.

2) The 32bit system call emulation layer does not properly ensure
that the requested system call is in the system call table, which can
be exploited to execute arbitrary code with kernel privileges.

This is related to:
SA26934

Successful exploitation requires 64bit systems.

SOLUTION:
Fixed in the GIT repository.

PROVIDED AND/OR DISCOVERED BY:
Ben Hawkes
