Buffer overflow in a DLL file in RealNetworks RealPlayer 10, RealPlayer 10.5 6.0.12.1040 through 6.0.12.1741, RealPlayer 11 11.0.0 through 11.0.4, RealPlayer Enterprise, Mac RealPlayer 10 and 10.1, Linux RealPlayer 10, and Helix Player 10.x allows remote attackers to execute arbitrary code via a crafted Internet Video Recording (IVR) file with a filename length field containing a large integer, which triggers overwrite of an arbitrary memory location with a 0x00 byte value, related to use of RealPlayer through a Windows Explorer plugin.

The remote host is running a version of RealPlayer earlier than RealPlayer SP 1.0.5.  Such versions are potentially affected by multiple vulnerabilities :

  - A RealPlayer 'ASM' Rulebook heap-based buffer overflow. (CVE-2009-4241)

  - A RealPlayer 'GIF' file heap overflow. (CVE-2009-4242)

  - A RealPlayer media overflow (http chunck encoding). (CVE-2009-4243)

  - A RealPlayer 'IVR' file processing buffer overflow. (CVE-2009-0375)

  - A RealPlayer 'IVR' file heap overflow. (CVE-2009-0376)

  - A RealPlayer 'SIPR' codec heap overflow. (CVE-2009-4244)

  - A RealPlayer compressed 'GIF' heap overflow. (CVE-2009-4245)

  - A RealPlayer 'SMIL' parsing heap overflow. (CVE-2009-4257)

  - A RealPlayer skin parsing stack overflow. (CVE-2009-4246)

  - A RealPlayer 'ASM' RuleBook array overflow. (CVE-2009-4247)

  - A RealPlayer 'rtsp' 'set_parameter' buffer overflow. (CVE-2009-4248)

Note that different versions are affected by different vulnerabilities.
