GTK+ up to 2.4.4 gdk-pixbuf io-xpm.c 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 was found in GTK+ up to 2.4.4. Affected by this vulnerability is an unknown code block of the file io-xpm.c of the component gdk-pixbuf. The manipulation with an unknown input leads to a stack-based overflow vulnerability. The CWE definition for the vulnerability is 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). As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Stack-based buffer overflow in xpm_extract_color (io-xpm.c) in the XPM image decoder for gtk+ 2.4.4 (gtk2) and earlier, and gdk-pixbuf before 0.22, may allow remote attackers to execute arbitrary code via a certain color string. NOTE: this identifier is ONLY for gtk+. It was incorrectly referenced in an advisory for a different issue (CVE-2004-0688).

The weakness was released 10/20/2004 by Chris Evans as confirmed advisory ( The advisory is shared at This vulnerability is known as CVE-2004-0783 since 08/17/2004. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Technical details are known, but no exploit is available.
