Descriptions

The RV20 codec in RealNetworks RealPlayer 11.x, 14.x, and 15.x before 15.02.71, and RealPlayer SP 1.0 through 1.1.5, does not properly handle the frame size array, which allows remote attackers to execute arbitrary code via a crafted RV20 RealVideo video stream.

El codec RV20 en RealNetworks RealPlayer v11.x, v14.x, v15.x, y anterior a v15.02.71, y RealPlayer SP v1.0 a v1.1.5, no controla correctamente el tamaño de la matriz de marco, que permite a atacantes remotos ejecutar código arbitrario a través de una secuencia de vídeo diseñado RV20 RealVideo.

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 or open a malicious file.
The specific flaw exists within how the application parses a particular array contained within a Real Media file and then uses the data. When allocating and reading frame size information, the application will fail to check the bounds of how this array is used. The application will use results in this array as an allocation for the size of a buffer. When initializing this new buffer, the application can then write outside it's bounds which will lead to code execution under the context of the application.
