Remote exploitation of a memory corruption vulnerability in RealNetworks Inc.'s RealPlayer media player could allow attackers to execute arbitrary code in the context of the targeted user.
The vulnerability specifically exists in the way RealPlayer handles specially crafted RealMedia files using the RealVideo Renderer plugin. When decoding a specially crafted RealMedia file, RealPlayer uses a value from the file without properly validating it, which leads to heap memory corruption and an exploitable condition.
