Users should apply the solution provided by RealNetworks.
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:
1) A heap corruption vulnerability that occurs when altering a field that determines the length of a structure.
2) 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.
