rjrmrpln.dll in RealNetworks RealPlayer 11.0 through 11.1, RealPlayer SP 1.0 through 1.1.4, and RealPlayer Enterprise 2.1.2 does not properly validate file contents that are used during interaction with a heap buffer, which allows remote attackers to execute arbitrary code via crafted Name Value Property (NVP) elements in logical streams in a media file.
Improper Input Validation The product receives input or data, but it does
not validate or incorrectly validates that the input has the
properties that are required to process the data safely and
correctly.
