RealOne player allows remote attackers to execute arbitrary script in the "My Computer" zone via a SMIL presentation with a URL that references a scripting protocol, which is executed in the security context of the previously loaded URL, as demonstrated using a "javascript:" URL in the area tag.
The PNG deflate algorithm in RealOne Player 6.0.11.x and earlier, RealPlayer 8/RealPlayer Plus 8 6.0.9.584, and other versions allows remote attackers to corrupt the heap and overwrite arbitrary memory via a PNG graphic file format containing compressed data using fixed trees that contain the length values 286-287, which are treated as a very large length.
Multiple buffer overflows in RealOne and RealPlayer allow remote attackers to execute arbitrary code via (1) a Synchronized Multimedia Integration Language (SMIL) file with a long parameter, (2) a long long filename in a rtsp:// request, e.g. from a .m3u file, or (3) certain "Now Playing" options on a downloaded file with a long filename.
Buffer overflow in Real Networks RealPlayer 8.0 and earlier allows remote attackers to execute arbitrary code via a header length value that exceeds the actual length of the header.
