+ <background>
+ <p>ktsuss is a simple, graphical version of su written in C and GTK+. </p>
+ </background>
+ <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>
