Debian: xconq buffer overflow vulnerabilities
Summary
Steve Kemp discovered a buffer overflow in xconq, in processing the
USER environment variable. In the process of fixing this bug, a
similar problem was discovered with the DISPLAY environment
variable. This vulnerability could be exploited by a local attacker
to gain gid 'games'.
For the current stable distribution (woody) this problem has been fixed
in version 7.4.1-2woody2.
For the unstable distribution (sid) this problem will be fixed soon.
Refer to Debian bug #202963.
We recommend that you update your xconq package.
