Vulerability Details

Windows Media Format ASF Parsing Vulnerability
CVE-2006-4702

A remote code execution vulnerability exists in Windows Media Format Runtime
due to the way it handles Advanced Systems Format (ASF) files. An attacker
could exploit the vulnerability by constructing specially crafted Windows
Media Player content that could potentially allow remote code execution if a
user visits a malicious Web site or opens an e-mail message with malicious
content. An attacker who successfully exploited this vulnerability could take
complete control of an affected system.

Windows Media Format ASX Parsing Vulnerability
CVE-2006-6134

A remote code execution vulnerability exists in Windows Media Format Runtime
due to the way it handles certain elements contained in Advanced Stream
Redirector (ASX) files. An attacker could exploit the vulnerability by
constructing a specially crafted ASX file that could allow remote code
execution if a user visits a malicious Web site, where specially crafted ASX
files are used to launch Windows Media player, or if a user clicks on a URL
pointing to a specially crafted ASX file. An attacker who successfully
exploited this vulnerability could take complete control of an affected system.
