CVE-2009-4309

Desbordamiento del búfer de la memoria dinámica en el codec Intel Indeo41 para Windows Media Player en Microsoft Windows 2000 SP4, XP SP2 y SP3, y Server 2003 SP2 permite a atacantes remotos ejecutar código arbitrario a través de un valor grande de tamaño en una grabación de película en un stream IV41 en un fichero multimedia, como se demuestra en un fichero AVI.

This vulnerability allows attackers to execute arbitrary code on vulnerable installations of Microsoft Windows Media Player. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the Intel Indeo41 codec which is accessed by various applications through the Video Compression Manager. This codec is registered to handle IV41 streams within a container such as the AVI format. Due to the lack of bounds checking on a specified size within the 'movi' record a heap overflow can occur. If successfully exploited this vulnerability can allow attackers to execute arbitrary code under the context of the user accessing the file.
