Package        : netris
Vulnerability  : buffer overflow
Problem-Type   : remote
Debian-specific: no
CVE Ids        : CAN-2003-0685

Shaun Colley discovered a buffer overflow vulnerability in netris, a
network version of a popular puzzle game.  A netris client connecting
to an untrusted netris server could be sent an unusually long data
packet, which would be copied into a fixed-length buffer without
bounds checking.  This vulnerability could be exploited to gain the
priviliges of the user running netris in client mode, if they connect
to a hostile netris server.

For the current stable distribution (woody) this problem has been fixed
in version 0.5-4woody1.

For the unstable distribution (sid) this problem is fixed in version
0.52-1.

We recommend that you update your netris package.
