Who is Vulnerable?
Vulnerability Description	IBM Lotus Sametime is an enterprise instant messaging and web conferencing application created by the Lotus Software division of IBM. Lotus Sametime provides enterprise instant messaging functionality, presence information, and web conferencing using standard protocols. The Lotus Sametime server runs on multiple platforms, including Microsoft Windows, IBM AIX, Mac OS, Sun Solaris and Linux-based operating systems. A stack-based buffer overflow vulnerability exists in the Community Services Multiplexer component of IBM Lotus Sametime. The vulnerability is the result of a boundary-check error during parsing of long URLs by the Community Services Multiplexer. A remote unauthenticated attacker can exploit this vulnerability for code execution by sending a specially crafted HTTP request to the target server. An attack targeting this vulnerability can result in the injection and execution of arbitrary code. If code execution is successful, the behaviour of the target will depend on the intention of the attacker. Any code injected will be executed within the security context of the affected service, normally System. In the case of an unsuccessful code execution attack, IBM Lotus Sametime Server will terminate resulting in a denial of service condition.
