    * Hyperlink Object Library Vulnerability - CAN-2005-0057: A remote code execution vulnerability exists in the Hyperlink Object Library. This problem exists because of an unchecked buffer while handling hyperlinks. An attacker could exploit the vulnerability by constructing a malicious hyperlink which could potentially lead to remote code execution if a user clicks a malicious link within a Web site or e-mail message. An attacker who successfully exploited this vulnerability could take complete control of the affected system. User interaction is required to exploit this vulnerability.

NTBugtraq Editor's Note:
Most viruses these days use spoofed email addresses. As such, using an Anti-Virus product which automatically notifies the perceived sender of a message it believes is infected may well cause more harm than good. Someone who did not actually send you a virus may receive the notification and scramble their support staff to find an infection which never existed in the first place. Suggest such notifications be disabled by whomever is responsible for your AV, or at least that the idea is considered.
