Descriptions

Heap-based buffer overflow in RealNetworks RealPlayer 11.0 through 11.1 and 14.0.0 through 14.0.5, RealPlayer SP 1.0 through 1.1.5, and RealPlayer Enterprise 2.0 through 2.1.5 allows remote attackers to execute arbitrary code via crafted ID3v2 tags in an MP3 file.

Una vulnerabilidad de desbordamiento de buffer basado en memoria dinámica (heap) en RealNetworks RealPlayer v11.0 a v11.1 y v14.0.0 a v14.0.5, RealPlayer SP v1.0 a v1.1.5, y RealPlayer Enterprise v2.0 a v2.1.5 permite a atacantes remotos ejecutar código de su elección a través de etiquetas ID3v2 debidamente modificadas en un archivo MP3.

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 the way RealPlayer handles ID3v2 Tags. RealPlayer creates a fixed size buffer for certain tags and will then populate them with the data from the file. It uses a call to WideCharToMultiByte to convert the data, but fails to take into account that converting a single wide char might result in more then two multi-byte chars. This causes more data to be written into the fixed buffer then anticipated resulting in a heap buffer overflow.
