October's Patch Tuesday's bigger than normal, with 11 security bulletins (four critical, six important, and one moderate) affecting the following desktop operating systems and applications:
Internet Explorer 5.01, 6, and 7 on Windows 2000 SP4, Windows XP, and Windows Vista get patched to stop a remote code execution threat
Windows XP SP2 and SP3 and Windows XP Professional x64 and XP Professional x64 SP2 will be patched to stop elevation of privilege attacks
Windows 2000 SP4 through Windows Vista SP1 will also be as updated needed to prevent remote code execution
Microsoft Excel 2000 SP3, Excel 2002, Excel 2003 SP2/SP3, and Excel 2007/2007 SP1 will be updated against a critical vulnerability, as will Excel Viewer 2003/2003 SP3, Excel Viewer, and MS Office Compatibility Pack and Compatibility Pack's SP1.
What else is coming down the chute starting Tuesday?
Windows Vista Media Center gets a pair of updates (one for the TV Pack, and one for everyone), as well as the usual updates to the Malicious Software Removal Tool, Windows Mail Junk Email Filter and Customer/Windows Vista Experience Improvement Program.
However, the biggest news is the premiere of the Microsoft Active Protections Program and Exploitability Index we told you about in August. Hopefully, these programs will aid the never-ending battle against the bad guys in cyberspace.
