-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2004.0226 -- ISS Security Brief Vulnerability in ICQ Parsing in ISS Products 19 March 2004 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: RealSecure Proventia BlackICE Publisher: ISS Impact: Execute Arbitrary Code/Commands Access Required: Remote - --------------------------BEGIN INCLUDED TEXT-------------------- - -----BEGIN PGP SIGNED MESSAGE----- Internet Security Systems Security Brief March 18, 2004 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 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 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.
