<p>
|
|
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, http://cve.mitre.org, has assigned CAN-2004-0001 to this issue.
|
|
</p>
|

|
|
<impact type="normal">
|
|
<p>
|
|
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.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no temporary workaround - a kernel upgrade is required. A list of
|
|
unaffected kernels is provided along with this announcement.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
Users are encouraged to upgrade to the latest available sources for
|
|
their system:
|
|
</p>
|
|
<code>
|
|
# 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.
|
|
</code>
|
|
<code>
|
|
# # IF YOUR KERNEL IS MARKED as "remerge required!" THEN
|
|
# # YOU SHOULD UPDATE YOUR KERNEL EVEN IF PORTAGE
|
|
# # REPORTS THAT THE SAME VERSION IS INSTALLED.
|
|
</code>
