Description
===========

A vulnerability has been discovered by Andi Kleen in the ptrace
emulation code for AMD64 platforms when eflags are processed, allowing a
local user to obtain elevated priveleges. The Common Vulnerabilities and
Exposures project has assigned CAN-2004-0001 to this issue.

======

( Only users of the AMD64 platform are affected )

In this scenario, a user may be able to obtain elevated priveleges,
including root access. However, no public exploit is known for the
vulnerability at this time.

Workaround
==========

There is no temporary workaround - a kernel upgrade is required. A list
of unaffected kernels is provided along with this announcement.

Resolution
==========

Users are encouraged to upgrade to the latest available sources for
their system:

~  # emerge sync
~  # emerge -pv your-favorite-sources

~  # emerge your-favorite-sources

~  # # Follow usual procedures for compiling and installing a kernel.
~  # # If you use genkernel, run genkernel as you would do normally.

~  # # See http://www.gentoo.org/doc/en/handbook/handbook.xml for help.
