Package        : xpcd
Vulnerability  : buffer overflow
Problem-Type   : local
Debian-specific: no
CVE Ids        : CAN-2003-0649

Steve Kemp discovered a buffer overflow in xpcd-svga which can be
triggered by a long HOME environment variable.  This vulnerability
could be exploited by a local attacker to gain root privileges.

For the stable distribution (woody) this problem has been fixed in
version 2.08-8woody1.

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

We recommend that you update your xpcd package.
