Package : bnc
Vulnerability : buffer overflow
Problem-Type : remote
Debian-specific: no
CVE ID : CAN-2004-1052

Leon Juranic discovered that BNC, an IRC session bouncing proxy, does
not always protect buffers from being overwritten. This could
exploited by a malicious IRC server to overflow a buffer of limited
size and execute arbitrary code on the client host.

For the stable distribution (woody) this problem has been fixed in
version 2.6.4-3.3.

This package does not exist in the testing or unstable distributions.

We recommend that you upgrade your bnc package.
