DNS: BIND Version Query
This protocol anomaly is a DNS query for version.bind with the type set to TXT and the class set to CHAOS. BIND servers support the ability to be remotely queried for their versions. This can indicate a reconnaisance attempt; when attackers know the BIND version, they can then attempt to exploit vulnerabilities on the server.
Extended Description
A buffer overflow exists in certain versions of BIND, the nameserver daemon currently maintained by the Internet Software Consortium (ISC). BIND fails to properly bound the data recieved when processing an inverse query. Upon a memory copy, portions of the program can be overwritten, and arbitrary commands run on the affected host. Exploits for this vulnerability are very widespread, and were posted to the Bugtraq mailing list.
