Descriptions

The drv2.dll (aka RV20 decompression) module in RealNetworks RealPlayer 11.0 through 11.1, RealPlayer SP 1.0 through 1.1.5, RealPlayer Enterprise 2.1.2 and 2.1.3, Linux RealPlayer 11.0.2.1744, and possibly HelixPlayer 1.0.6 and other versions, allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via a crafted value of an unspecified length field in an RV20 video stream.

El módulo drv2.dll (también conocido como descompresión RV20) en RealNetworks RealPlayer v11.0 a v11.1, RealPlayer SP v1.0 a v1.1.5, RealPlayer Enterprise v2.1.2 a v2.1.3 y Linux RealPlayer v11.0.2.1744 permite a atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (corrupción de la memoria montículo) a través de un valor modificado en un campo de longitud no especificada en una secuencia de vídeo RV20.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of RealNetworks RealPlayer. User interaction is required to exploit this vulnerability in that the target must visit a malicious page.
The specific flaw exists within the module responsible for decompressing RV20 video streams. The drv2.dll trusts a value from the file as a length and uses it within a copy loop that writes to heap memory. By specifying large enough values, heap memory can be corrupted which can lead to arbitrary code execution under the context of the user accessing the media file.
