Description


A vulnerability has been discovered in RealPlayer, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a signedness error in MPAMedia.dll when handling playlist names. This can be exploited to cause a stack-based buffer overflow by e.g. importing a file into a specified playlist with an overly long name via the "Import()" method of the IERPCtl ActiveX control (ierpplug.dll).

Successful exploitation allows execution of arbitrary code.

NOTE: The vulnerability is currently being actively exploited.
