Descriptions

Heap-based buffer overflow in RealNetworks RealPlayer 11.0 through 11.1, RealPlayer SP 1.0 through 1.1.1, Mac RealPlayer 11.0 through 11.1, and Linux RealPlayer 11.0.2.1744 allows remote attackers to execute arbitrary code via a large Screen Width value in the Screen Descriptor header of a GIF87a file in an RTSP stream.

Desbordamiento de búfer basado en montículo en RealNetworks RealPlayer v11.0 a v11.1, RealPlayer SP v1.0 a v1.1.1, Mac RealPlayer v11.0 a v11.1 y Linux RealPlayer v11.0.2.1744 permite a atacantes remotos ejecutar código arbitrario a través de un valor de Ancho de pantalla demasiado alto en la cabecera "Screen Descriptor" de un fichero GIF87a en un stream RTSP.

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 media file.
The specific flaw exists in the parsing of GIF87a files over the streaming protocol RTSP. When specifying a large Screen Width size in the Screen Descriptor header a calculation on the destination heap chunks size is improperly checked for overflow. This leads to a smaller buffer being allocated and subsequently a heap overflow when processing the received data. Exploitation of this vulnerability can lead to system compromise under the credentials of the currently logged in user.
