Today marks the monthly release of security and usability fixes from Microsoft, and this Patch Tuesday brought a number of important releases. MS's .NET Framework 1.1 received its first Service Pack, and "Critical" ratings were given to three updates - one for MS Word, one for Publisher, and the last for Windows - all of which dealt with Remote Code Execution issues. Also of note is an update to a number of Microsoft's security products - including Live OneCare and Defender - that patches a vulnerability in the Protection Engine that could allow a DoS attack. The full Security Bulletin is available here.
