RealNetworks RealPlayer/RealOne RT3 Plugin stack-based overflow

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability classified as critical has been found in RealNetworks RealPlayer and RealOne (Multimedia Player Software) (version now known). Affected is some unknown processing of the component RT3 Plugin. The manipulation with an unknown input leads to a stack-based overflow vulnerability. CWE is classifying the issue as CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Stack-based buffer overflow in the RT3 plugin, as used in RealPlayer 8, RealOne Player, RealOne Player 10 beta, and RealOne Player Enterprise, allows remote attackers to execute arbitrary code via a malformed .R3T file.

The bug was discovered 02/04/2004. The weakness was presented 03/07/2004 by Mark Litchfield with NGSSoftware (Website). The advisory is shared for download at service.real.com. This vulnerability is traded as CVE-2004-0387 since 04/09/2004. The exploitability is told to be difficult. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. There are neither technical details nor an exploit publicly available.

The vulnerability was handled as a non-public zero-day exploit for at least 32 days. During that time the estimated underground price was around $25k-$100k.
