Microsoft re-release DigiNotar security update

Microsoft has re-released a security update for Windows XP and Server 2003 after it has realized that the initial one - released last Tuesday in order to add six more DigiNotar root certificates to its Windows Untrusted Certificate Store - did not revoke all the certificates it planned to. This particular security update blocked only the latest six digital certificates cross-signed by GTE and Entrust, but did not contain the five DigiNotar root certificates that were blocked in two earlier updates. The mix-up left users vulnerable to man-in-the-middle attacks for almost the entire week. Microsoft advises users running Windows XP and Server 2003 to install this cumulative update.
