Package : xitalk Vulnerability : missing privilege release Problem-Type : local Debian-specific: no CVE ID : CAN-2004-0151

Steve Kemp from the GNU/Linux audit project discovered a problem in xitalk, a talk intercept utility for the X Window System. A local user can exploit this problem and execute arbitrary commands under the GID utmp. This could be used by an attacker to remove traces from the utmp file.

For the stable distribution (woody) this problem has been fixed in version 1.1.11-9.1woody1.

For the unstable distribution (sid) this problem will be fixed soon.

We recommend that you upgrade your xitalk package.
