DESCRIPTION

Microsoft has released a security bulletin and patch to address a security vulnerability that could allow a malicious user to gain control of an affected server.

Network Monitor, shipped with SMS Server 1.2, 2.0 and Windows 2000 Server versions, contains a protocol parser that aids in interpreting and analyzing previously captured network data.  If a malicious user was to send a specially crafted frame to a server that was monitoring network traffic it would cause an overflow that would cause Network Monitor to crash and allow the malicious user to launch arbitrary commands.
