Package : xonix
Vulnerability : failure to drop privileges
Problem-Type : local
Debian-specific: no
CVE Ids : CAN-2004-0157

Steve Kemp discovered a vulnerability in xonix, a game, where an external program was invoked while retaining setgid privileges. A local attacker could exploit this vulnerability to gain gid "games".

For the current stable distribution (woody) this problem will be fixed in version 1.4-19woody1.

We recommend that you update your xonix package.
