NSC-040315: W32.Witty.Worm Attacking Black Ice Internet Firewall

A new wormed named W32.Witty.Worm has been spreading across 
campus.  W32.Witty.Worm utilizes a Vulnerability in ICQ Parsing by ISS 
Products. The worm sends itself out to multiple IP addresses on source port 
4000/UDP and a random destination port,  this traffic typically saturates 
the local network connections.  This saturation has been the cause of a 
number of network problems in the last 24 hours across campus.
In order to keep the overall network operational ITS has had to disabled 
the infected machines.

The following products are vulnerable:

RealSecure® Network 7.0, XPU 22.11 and before
RealSecure Server Sensor 7.0 XPU 22.11 and before
RealSecure Server Sensor 6.5 for Windows SR 3.10 and before
Proventia™ A Series XPU 22.11 and before
Proventia G Series XPU 22.11 and before
Proventia M Series XPU 1.9 and before
RealSecure Desktop 7.0 ebl and before
RealSecure Desktop 3.6 ecf and before
RealSecure Guard 3.6 ecf and before
RealSecure Sentry 3.6 ecf and before
BlackICE™ Agent for Server 3.6 ecf and before
BlackICE PC Protection 3.6 ccf and before
BlackICE Server Protection 3.6 ccf and before

The worm is a memory-only based threat and does not create files on the 
system, but has a payload that overwrites random sectors of a random hard disk.

NOTE: If your system is not running a vulnerable version of one of the 
products affected, then you will not be infected.

If you are running a product that has the vulnerability used by the worm, 
we recommend that you apply the relevant patch as soon as possible. Patches 
for this vulnerability are available at http://blackice.iss.net/update_center/index.php.
