Descriptions
Heap-based buffer overflow in qcpfformat.dll in RealNetworks RealPlayer 11.0 through 11.1 and 14.0.0 through 14.0.5 and RealPlayer SP 1.0 through 1.1.5 allows remote attackers to execute arbitrary code via a crafted QCP file.
Desbordamiento de buffer basado en memoria dinámica (heap) en qcpfformat.dll en RealNetworks RealPlayer v11.0 a v11.1 y v14.0.0 a v14.0.5, y RealPlayer SP v1.0 a v1.1.5 permite a atacantes remotos ejecutar código de su elección mediante un archivo QCP debidamente modificado.
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 qcpfformat.dll, which is responsible for parsing QCP media files. The process creates a static 256 byte allocation on the heap and trusts a user-supplied counter from the file within a memory copy loop. As the source data is also user-supplied from the file, this can be abused by a remote attacker to execute arbitrary code running in the context of the web browser.
