|
|
Multiple memory corruption vulnerabilities have been found in the
|
|
ProcDbeGetVisualInfo() and the ProcDbeSwapBuffers() of the DBE
|
|
extension, and ProcRenderAddGlyphs() in the Render extension.

<impact type="normal">
|
|
<p>
|
|
A local attacker could execute arbitrary code with the privileges of
|
|
the user running the X server, typically root.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
Disable the DBE extension by removing the "Load dbe" directive in the
|
|
Module section of xorg.conf, and explicitly disable the Render
|
|
extension with ' Option "RENDER" "disable" ' in the Extensions section.
|
|
</p>
|
|
<p>
|
|
Note: This could affect the functionality of some applications.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All X.Org X server users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=x11-base/xorg-server-1.1.1-r4"</code>
