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.
Solution:
Apply patch for RealPlayer 10.5 and 11 beta:
http://service.real.com/realplayer/security/191007_player/en/securitydb.rnx
The vendor recommends users of RealPlayer 10 and RealOne v1 and v2 to upgrade to version 10.5 and apply the patch.
NOTE: According to the vendor, RealPlayer 8 and prior versions for Windows are not affected. Versions for Macintosh and Linux are also not affected.
