Technical Description:
----------------------
* JPEG Image Rendering Memory Corruption Vulnerability - CAN-2005-1988 A remote code execution vulnerability exists in Internet Explorer because of the way that it handles JPEG images. An attacker could exploit the vulnerability by constructing a malicious JPEG image that could potentially allow remote code execution if a user visited a malicious Web site or viewed a malicious e-mail message. An attacker who successfully exploited this vulnerability could take complete control of an affected system.

* Web Folder Behaviors Cross-Domain Vulnerability - CAN-2005-1989: A cross-domain vulnerability exists in Internet Explorer that could allow information disclosure or remote code execution on an affected system. An attacker could exploit the vulnerability by constructing a malicious Web page. The malicious Web page could potentially allow remote code execution if it is viewed by a user. An attacker who successfully exploited this vulnerability could take complete control of an affected system. However, significant user interaction and social engineering is required to exploit this vulnerability.

* COM Object Instantiation Memory Corruption Vulnerability - CAN-2005-1990: A remote code execution vulnerability exists in the way Internet Explorer instantiates COM Objects that are not intended to be used in Internet Explorer. An attacker could exploit the vulnerability by constructing a malicious Web page that could potentially allow remote code execution if a user visited the malicious Web site. An attacker who successfully exploited this vulnerability could take complete control of an affected system.

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.
