Some vulnerabilities have been reported in RealPlayer, which potentially can be exploited by malicious people to disclose certain information or compromise a user's system.

1) An error in the rmoc3260 ActiveX control when handling the "Controls", "Console", or "WindowName" properties with a specific timing can be exploited to cause a memory corruption.

This is reportedly similar to:
SA29315

2) An unspecified error can be exploited to reference local resources.

3) A design error within the handling of frames in Shockwave Flash (SWF) files can be exploited to cause a heap-based buffer overflow.

4) A boundary error in rjbdll.dll can be exploited to cause a stack-based buffer overflow by importing a media library file using an ActiveX control and deleting the imported file.

Successful exploitation of the vulnerabilities allow execution of arbitrary code.
