Unspecified vulnerability in the RV40 codec in RealNetworks RealPlayer 11.x, 14.x, and 15.x before 15.02.71, and RealPlayer SP 1.0 through 1.1.5, allows remote attackers to execute arbitrary code via a crafted RV40 RealVideo video stream.

RealNetworks RealPlayer 11.x, 14.x, and 15.x before 15.02.71, and RealPlayer SP 1.0 through 1.1.5, allows remote attackers to execute arbitrary code via vectors involving a VIDOBJ_START_CODE code in a header within a video stream.

The RV20 codec in RealNetworks RealPlayer 11.x, 14.x, and 15.x before 15.02.71, and RealPlayer SP 1.0 through 1.1.5, does not properly handle the frame size array, which allows remote attackers to execute arbitrary code via a crafted RV20 RealVideo video stream.

rvrender.dll in RealNetworks RealPlayer 11.x, 14.x, and 15.x before 15.02.71, and RealPlayer SP 1.0 through 1.1.5, allows remote attackers to execute arbitrary code via crafted flags in an RMFF file.

Buffer overflow in common/util/rlstate.cpp in Helix Player 1.0.6 and RealPlayer allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a RuleBook structure with a large number of rule-separator characters that trigger heap memory corruption.
