Package        : zblast
Vulnerability  : buffer overflow
Problem-Type   : local
Debian-specific: no
CVE Ids        : CAN-2003-0613

Steve Kemp discovered a buffer overflow in zblast-svgalib, when saving
the high score file.  This vulnerability could be exploited by a local
user to gain gid 'games', if they can achieve a high score.

For the current stable distribution (woody) this problem has been fixed
in version 1.2pre-5woody2.

For the unstable distribution (sid) this problem is fixed in version
1.2.1-7.

We recommend that you update your zblast package.
