Who is Vulnerable?
Vulnerability Description Lotus Notes is a client-server collaborative software and email system provided by IBM. The Lotus Notes email client application is capable of communicating with email servers over a range of protocols, such as: SMTP, POP, and IMAP. A stack buffer overflow vulnerability exists in the way IBM Lotus Notes Attachment Viewer processes files. The vulnerability is a result of insufficient boundary checking while processing the Microsoft Word for DOS Document. A remote attacker can exploit this vulnerability by enticing the target user to open a crafted Word for DOS file, potentially causing arbitrary code to be injected and executed in the security context of the current user. An attack targeting this vulnerability can result in the injection and execution of code. If code execution is successful, the behavior of the target will depend on the intention of the attacker. Any code injected will be executed within the security context of the currently logged in user. In an attack case where code execution is unsuccessful, Lotus Notes will terminate.
