Vulnerable Systems:
* RealNetworks RealPlayer
The specific flaw exists when parsing a RealMedia file containing a malformed Media Properties Header (MDPR). The application explicitly trusts an index in this data structure which is used to seek into an array of objects. If an attacker can allocate controlled data at some point after this array, an attacker can then get their fabricated object to get called leading to code execution under the context of the current user.
