RealOne Player Gold and RealJukebox2 RJS skin file "CONTROLnImage" buffer overflow

realplayer-rjs-controlnimage-bo (9538) The risk level is classified as HighHigh Risk

Description:

RealNetwork RealOne Player Gold is vulnerable to a buffer overflow in the processing of RJS skin files. By specifying an overly long file name in the "CONTROLnImage" field of the skin.ini file and then compressing this file to create an RJS file, a remote attacker could overflow a buffer and execute arbitrary code on the victim's system once the RJS file is opened. An attacker could exploit this vulnerability by creating a malicious Web page or sending a victim a malicious HTML email that could either cause the RJS file to be opened automatically or provide a URL link that would cause the malicious RJS file to be opened when clicked.
