Package        : xconq
Vulnerability  : buffer overflows
Problem-Type   : local
Debian-specific: no
CVE Ids        : CAN-2003-0607

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.
