Description:   Several vulnerabilities were reported in RealPlayer. A remote user can cause arbitrary code to be executed on the target user's system.

A remote user can create specially crafted media content that, when loaded by the target user, will execute arbitrary code on the target system. The code will run with the privileges of the target user.

A specially crafted ASM RuleBook can trigger a heap overflow [CVE-2009-4241].

A specially crafted GIF file can trigger a heap overflow [CVE-2009-4242].

Media with specially crafted HTTP chunk encoding can trigger code execution [CVE-2009-4243].

A specially crafted media file can trigger a heap overflow in the SIPR Code [CVE-2009-4244].

A specially crafted compressed GIF file can trigger a heap overflow [CVE-2009-4245].

A specially crafted skin file can trigger a stack overflow [CVE-2009-4246].

A specially crafted ASM RuleBook can trigger an overflow [CVE-2009-4247].

A specially crafted RTSP set_parameter value can trigger a buffer overflow [CVE-2009-4248].

A specially crafted SMIL file can trigger a heap overflow [CVE-2009-4257].

Evgeny Legerov, anonymous researchers via iDEFENSE Labs, and John Rambo and anonymous researchers via TippingPoint's Zero Day Initiative reported these vulnerabilities.

Impact:   A remote user can create media content that, when loaded by the target user, will execute arbitrary code on the target user's system.
