DNS Probe and (?) Exploit Attempt

[Crist Clark <crist.clark () GLOBALSTAR COM>]

Last night, a skr1pt k1dd13 scan walked across a number of subnets.
Some packets did end up getting to real DNS servers but passed by
some IDSes in the process. The signature is,

The first one is obvious. But after combing kiddie sites all morning,
have not been able to match that second inverse-query to a known tool
or exploit method. Anyone recognize that signature and what BIND (I
assume) bug that is going after? Before anyone points to IDS277 at
whitehats.com, that does not look like the signature of the tool cited
in the notes for the rule.

Thanks for any help.
