Debian DSA-595-1 : bnc - buffer overflow

critical Nessus Plugin ID 15824

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the bnc package.

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.
