Comment 2 Tomas Hoger 2012-07-25 10:52:36 UTC 
This CVE may be a full or partial duplicate of CVE-2012-2750 (bug #833742).  Upstream is unlikely to provide any further info, so we can't be sure.
Comment 3 Tomas Hoger 2012-08-03 09:50:22 UTC 
A possible candidate for this issue is the following change:

http://bazaar.launchpad.net/~mysql/mysql-server/5.1/revision/3695
Bug#13012483:EXPLAIN EXTENDED, PREPARED STATEMENT, CRASH IN CHECK_SIMPLE_EQUALITY
