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 RealJukebox 2 1.0.2.340 and 1.0.2.379, and RealOne Player Gold 6.0.10.505, allows remote attackers to execute arbitrary code via an RFS skin file whose skin.ini contains a long value in a CONTROLnImage argument, such as CONTROL1Image.

RealJukebox 2 1.0.2.340 and 1.0.2.379, and RealOne Player Gold 6.0.10.505, allows remote attackers to execute arbitrary script in the Local computer zone by inserting the script into the skin.ini file of an RJS archive, then referencing skin.ini from a web page after it has been extracted, which is parsed as HTML by Internet Explorer or other Microsoft-based web readers.

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.
