Microsoft has released two new important updates - rated critical by the Redmond based Software giant - for Internet Explorer and Outlook Express. Affected versions range from version 5.01 to 6 SP1 of Internet Explorer where a security vulnerability has been identified that could allow an attacker to compromise your Windows-based computer and, possibly, read files on it. A similar vulnerability exists in Outlook Express. I have added both updates to our Internet Explorer Post SP1 Updates chart. Users of other versions than IE 6 SP1 and OE SP1 please consult Windows Update.
