Microsoft Windows Media Format Runtime ASF handling buffer overflow

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.
