Vulnerability Description
A remote code execution vulnerability has been identified in Microsoft Windows Media Player which is an application for Windows that supports numerous video, audio, and image formats. A remote attacker could exploit this issue via a malformed SAMI file. Microsoft Synchronized Accessible Media Interchange (SAMI) is designed to simplify creating captions for media playback on a PC. SAMI captions coexist with digital media as separate, simple text files. Successful exploitation of this vulnerability may allow execution of arbitrary code on a target system.
