Microsoft released just two updates on Tuesday as part of a light patch
Tuesday, especially in comparison with April’s 11 bulletins.
May’s batch contains a fix (MS10-030) for a critical vulnerability in Windows
Outlook Express, Windows Mail and Windows Live Mail. Left unchecked, the
vulnerability created a mechanism for remote code execution.
The second bulletin (MS10-03) covers a remote code execution flaw in
supported versions of Microsoft Office, and is labelled as "important".
