<description>
|
|
<p>Two vulnerabilities have been found in ktuss:</p>
|
|
|
|
<ul>
|
|
<li>Under specific circumstances, ktsuss skips authentication and fails
|
|
to change the effective UID back to the real UID (CVE-2011-2921).
|
|
</li>
|
|
<li>The GTK interface spawned by the ktsuss binary is run as root
|
|
(CVE-2011-2922).
|
|
</li>
|
|
</ul>
|
|
</description>
|
|
<impact type="high">
|
|
<p>A local attacker could gain escalated privileges and use the
|
|
"GTK_MODULES" environment variable to possibly execute arbitrary code
|
|
with root privileges.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>There is no known workaround at this time.</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>Gentoo discontinued support for ktsuss. We recommend that users unmerge
|
|
ktsuss:
|
|
</p>
|
|
|
|
<code>
|
|
# emerge --unmerge "x11-misc/ktsuss"
|
|
</code>
