Overview
Microsoft Windows Media Format Runtime is vulnerable to a heap-based buffer overflow. This vulnerability may allow a remote, unauthenticated attacker to execute arbitrary code on an vulnerable system.
Description
Microsoft Windows Media Format Runtime is used by various Windows Media applications such as Windows Media Player. The Windows Media Format Runtime includes the ability to play Advanced Systems Format (ASF) files, which can contain streaming audio, video, slide shows and synchronized events. A heap-based buffer overflow exists due to Microsoft Windows Media Format Runtime's improper parsing of ASF files. By successfully persuading a user to access a specially crafted ASF file, a remote, unauthenticated attacker could trigger the buffer overflow. |
Impact
A remote, unauthenticated attacker could execute arbitrary code on a vulnerable system. |
Solution
Microsoft has published Microsoft Security Bulletin MS07-068 in response to this issue. Users are strongly encouraged to review this bulletin and apply the referenced patches. |
