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 communication with email servers over the SMTP, POP and IMAP protocols. A stack buffer overflow vulnerability exists in the IBM Lotus Notes HTML Speed Reader component. The flaw is triggered by an overly long link URL contained in an email. An attacker may exploit this issue to inject and execute arbitrary code on the target host system with the privileges of the user running the affected application. In case of an attack where code injection is not successful, the affected Lotus Notes client will terminate, creating a denial of service condition. The Notes client can not be resumed until the system is rebooted. In case of an attack where code injection and execution is successful, the behavior of the system is dependent on the intended purpose of the injected code. Any code injected into the vulnerable component would execute in the security context of the currently logged in user.
