VULNERABILITY DETAILS

This vulnerability allows attackers to execute arbitrary code on vulnerable installations of RealNetworks RealPlayer. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

The specific flaw exists within RealPlayer's parsing of IVR files. The process trusts size values present in the file and uses them unsafely in various file I/O and memory allocation operations. A specially crafted file can cause memory overflows to occur leading to arbitrary code execution under the context of the user running the player.

ADDITIONAL DETAILS RealNetworks has issued an update to correct this vulnerability. More details can be found at:
