CVE-2010-3750

rjrmrpln.dll en RealNetworks RealPlayer v11.0 hasta la v11.1, RealPlayer SP 1.0 hasta la v1.1.4, y RealPlayer Enterprise v2.1.2 no valida apropiadamente el contenido de un fichero utilizado durante la interacción con un desbordamiento de memoria dinámica, lo que permite a atacantes remotos ejecutar código de su elección a través de elementos "Name Value Property" (NVP) en streams lógicos de un archivo multimedia.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of RealNetworks RealPlayer. User interaction is required in that a target must open a malicious website or media file.
The specific flaw exists within the code responsible for parsing Name Value Property (NVP) elements from within logical streams in a RealPlayer media file. Specifically, a function within the rjrmrpln.dll file allocates a buffer on the heap which can be directly influenced from data within the file. This buffer is then written to using another value defined in the file and thus also controlled. By crafting a malicious media file an attacker can abuse this to execute arbitrary code under the context of the user running the player.
