Fortinet's FortiGuard Global Security Research Team has discovered two vulnerabilities in RealPlayer, which allow a remote attacker to compromise a system through a malicious media clip.
Remote code execution.
- RealNetworks RealPlayer 11
Internet Video Recording (IVR) files contain media content that is played and recorded by RealPlayer. A remote attacker could craft a malicious IVR file, that when sent to an unsuspecting user, may allow the execution of arbitrary code when viewed, using one of two vulnerabilities during RealPlayer's IVR processing routine:
- A heap corruption vulnerability that occurs when altering a field that determines the length of a structure
- A vulnerability that allows an attacker to write one null byte to an arbitrary memory address by using an overly long file name length value
- The FortiGuard Global Security Research Team released the signature "RealNetworks.RealPlayer.IVR.File.Processing.Code.Execution"
