Descriptions
RealNetworks RealPlayer before 15.0.0 allows remote attackers to execute arbitrary code via a crafted QCELP stream.
RealNetworks RealPlayer anterior a v15.0.0 permite a atacantes remotos ejecutar código arbitrario a través de una corriente QCELP.
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 audio encoded with the QCELP codec. The codec allows you to specify the 'block_size' that is used. This size is used to create an allocation to hold the data, but a hardcoded blocksize is later used to copy data into that allocation. This could lead to remote code execution under the context of the current user.
