SQL Server security issues

Microsoft Security Bulletin http://www.microsoft.com/technet/security/bulletin/ms09-004.mspx issued in February 2009 is not an issue if you have SQL Server 2005 SP3 installed.

GO
NOTE: don’t use this with Transactional Replication with Updateable Subscriptions

The other fairly recent security issue from July 2008 is
