LibAST is a utility library that was originally intended to accompany
Eterm, but may be used by various other applications.

<description>
<p>
Michael Jennings discovered an exploitable buffer overflow in the
configuration engine of LibAST.
</p>
</description>
<impact type="high">
<p>
The vulnerability can be exploited to gain escalated privileges if the
application using LibAST is setuid/setgid and passes a specifically
crafted filename to LibAST's configuration engine.
</p>
</impact>
<workaround>
<p>
Identify all applications linking against LibAST and verify they are
not setuid/setgid.
</p>
</workaround>
<resolution>
<p>
All users should upgrade to the latest version and run revdep-rebuild:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=x11-libs/libast-0.7&quot;
# revdep-rebuild</code>
</resolution>
