Description Vincent Danen 2010-10-06 22:10:04 UTC 
A flaw in MySQL versions prior to 5.1.51 [1] was reported [2] that could allow an authenticated user to kill connections to MySQL by using GROUP_CONCAT() together with 'WITH ROLLUP'.

[1] http://dev.mysql.com/doc/refman/5.1/en/news-5-1-51.html
[2] http://bugs.mysql.com/bug.php?id=54476

This is noted as having been fixed in MySQL 5.1.51, but it does not cause a crash on MySQL 5.0.50 in Fedora 13.  It also causes a crash on Red Hat Enterprise Linux 5 (5.0.77) but not Red Hat Enterprise Linux 4 (4.1.22).  GROUP_CONCAT() support looks to have been added in MySQL 4.1, so Red Hat Enterprise Linux 3 is not affected.

A patch for this flaw is included in the upstream report.
