Stack-based buffer overflow in the SmilTimeValue::parseWallClockValue function in smlprstime.cpp in RealNetworks RealPlayer 10, 10.1, and possibly 10.5, RealOne Player, RealPlayer Enterprise, and Helix Player 10.5-GOLD and 10.0.5 through 10.0.8, allows remote attackers to execute arbitrary code via an SMIL (SMIL2) file with a long wallclock value.

Buffer overflow in swfformat.dll in multiple RealNetworks products and versions including RealPlayer 10.x, RealOne Player, Rhapsody 3, and Helix Player allows remote attackers to execute arbitrary code via a crafted SWF (Flash) file with (1) a size value that is less than the actual size, or (2) other unspecified manipulations.

Heap-based buffer overflow in the embedded player in multiple RealNetworks products and versions including RealPlayer 10.x, RealOne Player, and Helix Player allows remote malicious servers to cause a denial of service (crash) and possibly execute arbitrary code via a chunked Transfer-Encoding HTTP response in which either (1) the chunk header length is specified as -1, (2) the chunk header with a length that is less than the actual amount of sent data, or (3) a missing chunk header.

Stack-based buffer overflow in the RT3 plugin, as used in RealPlayer 8, RealOne Player, RealOne Player 10 beta, and RealOne Player Enterprise, allows remote attackers to execute arbitrary code via a malformed .R3T file.

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.
