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.

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
