Vulnerability in ICQ Parsing in ISS Products	

Synopsis:

A vulnerability was discovered in the ICQ instant messaging protocol 
parsing routines of the ISS Protocol Analysis Module (PAM) component. 
The PAM module is a shared component of all current ISS host, server, 
and network protection software and devices. The flaw relates to 
incorrect parsing of the ICQ protocol which may lead to a buffer 
overflow condition.

Affected Versions:

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 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

Updates are available from the ISS Download Center: http://www.iss.net/download/

Impact:

The vulnerability is caused by insufficient size checks on certain 
protocol fields in ICQ response data. After examining the nature of 
this vulnerability, ISS X-Force believes that exploitation of this 
issue is possible. It would not be necessary for ICQ response data to 
be part of a legitimate ICQ session to trigger this issue.
