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 Lotus Domino server, as well as Internet email gateways using SMTP, POP, and IMAP protocols. A stack buffer overflow vulnerability exists in IBM Lotus Notes. The vulnerability is a result of insufficient boundary checking while parsing HTML formatted email. A remote attacker can exploit this vulnerability by persuade the target user to perform certain operation upon a crafted email message, potentially causing arbitrary code to be injected and executed in the security context of the current user. In an attack case where code injection is not successful, all instances of the vulnerable IBM Lotus Notes application will terminate. In a more sophisticated attack scenario where code injection is successful, the behavior of the target host is entirely dependent on the intended function of the injected code. The code in such a case would execute within the security context of the current user. The affected application would also most likely stop functioning as a result of such an attack.
