Security Breach in MCIS Mail Server Fixed

Microsoft has discovered and fixed a security violation in the Microsoft Commercial Internet System (MCIS) Mail server. The vulnerability could allow a malicious user to remotely cause services on the server to fail, or cause arbitrary code to run on the server.

The IMAP service included in MCIS Mail has an unchecked buffer. If a malformed request containing random data were passed to the service, it could cause the Web publishing, IMAP, SMTP, LDAP, and other services to crash. If the malformed request contained specially crafted data, it could also be used to run arbitrary code on the server via a classic buffer overrun attack.

Microsoft Commercial Internet System 2.0 and 2.5 are affected by this vulnerability. The Intel version of the patch is available at http://www.microsoft.com/Downloads/Release.asp?ReleaseID=17124 and the Alpha version is available at http://www.microsoft.com/Downloads/Release.asp?ReleaseID=17122. -- Isaac Slepner
