[GLSA-200402-06] Updated kernel packages fix the AMD64 ptrace vulnerability

Vulnerability Assessment Summary
Updated kernel packages fix the AMD64 ptrace vulnerability

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200402-06
(Updated kernel packages fix the AMD64 ptrace vulnerability)

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

Impact

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.

Solution:
Users are encouraged to upgrade to the latest available sources for
their system:
# emerge sync
# emerge -pv your-favourite-sources
# emerge your-favourite-sources
# # Follow usual procedure for compiling and installing a kernel.
# # If you use genkernel, run genkernel as you would do normally.
# # IF YOUR KERNEL IS MARKED as "remerge required!" THEN
# # YOU SHOULD UPDATE YOUR KERNEL EVEN IF PORTAGE
# # REPORTS THAT THE SAME VERSION IS INSTALLED.

Network Security Threat Level: Medium
