Synopsis:	Important: kernel security update
Issue date:	2010-09-21
CVE Names:	CVE-2010-3081

This update fixes the following security issue:

* The compat_alloc_user_space() function in the Linux kernel 32/64-bit
compatibility layer implementation was missing sanity checks. This
function could be abused in other areas of the Linux kernel if its
length argument can be controlled from user-space. On 64-bit systems, a
local, unprivileged user could use this flaw to escalate their
privileges. (CVE-2010-3081, Important)

The system must be rebooted for this update to take effect.

SL 5.x
