Technical Description: ---------------------- * PNG Image Rendering Memory Corruption Vulnerability - CAN-2005-1211 A remote code execution vulnerability exists in Internet Explorer because of the way that it handles PNG images. An attacker could exploit the vulnerability by constructing a malicious PNG 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. * XML Redirect Information Disclosure Vulnerability - CAN-2002-0648 An information disclosure vulnerability exists in Internet Explorer because of the way that it handles certain requests to display XML content. An attacker could exploit the vulnerability by constructing a malicious Web page that could potentially lead to information disclosure if a user visited a malicious Web site or viewed a malicious e-mail message. An attacker who successfully exploited this vulnerability could read XML data from another Internet Explorer domain. However, user interaction is required to exploit this vulnerability.

(v4.01.1975.38886) Cheers, Russ Cooper - Senior Scientist - Cybertrust/NTBugtraq Editor -- 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. --
