within the resolver code makes it possible to overwrite stack variables by generating a malformed DNS packet. This problem makes it possible to create a situation where a malicious user may be able to execute code remotely with the UID and GID of the BitchX client. It is necessary for an attacker to control their own DNS to exploit this bug.
