http://www.oracle.com/technetwork/topics/security/cpuapr2013-1899555.html#AppendixMSQL
This update contains 25 security fixes for MySQL. Presumably they will be fixed in versions 5.1.69, 5.5.31, and 5.6.11 however there are no new releases on dev.mysql.com as of yet.
These issues affect 5.1.68 and earlier, 5.5.30 and earlier, 5.6.10 and earlier (not all issues are applicable to each, however; individual CVE bugs will be filed for each issue).
