Zero Day Initiative Advisory 11-332

Zero Day Initiative Advisory 11-332 - This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of RealNetworks Realplayer. AUser 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 AAC files. When parsing an AAC file, Realplayer will create buffers based on the type of Channel it finds in the first frame. When the AAC starts with a Single channel in the first frame, and then changes to a channel pair in the following frame, Realplayer fails to update the buffer size for the channel data. The buffer overwrite that follows could result in remote code execution under the context of the current user.
