Synopsis ========
Two vulnerabilities have been found in ktsuss, allowing local attackers to gain escalated privileges.
Background ==========
ktsuss is a simple, graphical version of su written in C and GTK+.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 x11-misc/ktsuss <= 1.4 Vulnerable! ------------------------------------------------------------------- NOTE: Certain packages are still vulnerable. Users should migrate to another package if one is available or wait for the existing packages to be marked stable by their architecture maintainers.
Description ===========
Two vulnerabilities have been found in ktuss:
* Under specific circumstances, ktsuss skips authentication and fails to change the effective UID back to the real UID (CVE-2011-2921). * The GTK interface spawned by the ktsuss binary is run as root (CVE-2011-2922).
Impact ======
A local attacker could gain escalated privileges and use the "GTK_MODULES" environment variable to possibly execute arbitrary code with root privileges.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
Gentoo discontinued support for ktsuss. We recommend that users unmerge ktsuss:
# emerge --unmerge "x11-misc/ktsuss"
