Mandriva Linux Security Advisory 2010-223 - Multiple vulnerabilities were discovered and corrected in mysql. During evaluation of arguments to extreme-value functions (such as LEAST() and GREATEST()), type errors did not propagate properly, causing the server to crash. The server could crash after materializing a derived table that required a temporary table for grouping. 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. Pre-evaluation of LIKE predicates during view preparation could cause a server crash. Various other issues were addressed as well.
