<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 ">=x11-libs/libast-0.7"
|
|
# revdep-rebuild</code>
|
|
</resolution>
