IIS Cumulative Patch Released

Microsoft Corp. issued a cumulative patch this week for its Internet Information Services Web server that fixes four critical new vulnerabilities and six other newly discovered bugs.

It is the largest collections of new bug fixes for IIS outside of a service pack in the last two years. The last cumulative patch for IIS was in August and fixed five flaws. A May 2001 cumulative patch rollup fixed three problems.

As a cumulative patch, the fix also includes all previously released fixes for the standalone IIS 4.0; IIS 5.0, which ships in Windows 2000; and IIS 5.1, which ships in Windows XP Professional Edition. Microsoft says it didn't include Windows .NET Server's IIS 6.0 in the general patch because it is a beta product and is not intended for production use. Microsoft was sending fixes directly to the limited number of customers officially running IIS 6.0 in production environments.

The security bulletin and patch are available at http://www.microsoft.com/technet/treeview/default.asp?url=/technet/security/bulletin/ms02-018.asp.

All four of the critical flaws involve buffer overflows. The other problems involve cross-site scripting, a denial of service via an FTP status request and an access violation in URL error handling.
