Mandriva Linux Security Advisory – MySQL 5.x before 5.0.36 allows local users to cause a denial of service (database crash) by performing information_schema table subselects and using ORDER BY to sort a single-row result, which prevents certain structure elements from being initialized and triggers a NULL dereference in the filesort function. This issue does not affect MySQL 5.0.37 in Mandriva Linux 2007.1. The in_decimal::set function in item_cmpfunc.cc in MySQL before 5.0.40, and 5.1 before 5.1.18-beta, allows context-dependent attackers to cause a denial of service (crash) via a crafted IF clause that results in a divide-by-zero error and a NULL pointer dereference. MySQL before 4.1.23, 5.0.x before 5.0.42, and 5.1.x before 5.1.18 does not require the DROP privilege for RENAME TABLE statements, which allows remote authenticated users to rename arbitrary tables.
