Microsoft released three patches – two of which it deems critical - on Tuesday in the May edition of its regular Patch Tuesday update cycle.

Most seriously there’s a critical vulnerability in Microsoft Exchange which allows remote code execution (MS06-019). This security bug in Microsoft Exchange’s calendar function could lead to a worm, security tools firm ISS warns.

A new round of Bagle worm updates are going out to already-infected PCs, a security company warned Monday, and although one site spewing out the new versions has been shut down, another has popped up.
