Subject: Re: CVE request, security issues fixed in MySQL 5.1.51

Looks like there were 8 security bugs reported at, not 7.

These all have different affected versions claimed, so each gets a 
separate CVE.

Bug#55826 - incorrect propagation of type errors in evaluation of
arguments to extreme-value functions

   "create table .. select crashes with when KILL_BAD_DATA is returned"

Bug#55568 - The server could crash after materializing a derived table
that required a temporary table for grouping.

   "user variable assignments crash server when used within query"

Bug #55564 - A user-variable assignment expression that is evaluated
in a logical expression context can be precalculated in a temporary
table for GROUP BY. However, when the expression value is used after
creation of the temporary table, it was re-evaluated, not read from
the table and a server crash resulted.

   5.0.91,5.1.47, 5.5.3, 5.5.5-m3
