Python up to 2.5.1 imageop.c numeric error

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 was found in Python (Programming Language Software). It has been declared as critical. This vulnerability affects an unknown part of the file imageop.c. The manipulation with an unknown input leads to a numeric error vulnerability. The CWE definition for the vulnerability is CWE-189. As an impact it is known to affect confidentiality, and availability. CVE summarizes:

Multiple integer overflows in the imageop module in Python 2.5.1 and earlier allow context-dependent attackers to cause a denial of service (application crash) and possibly obtain sensitive information (memory contents) via crafted arguments to (1) the tovideo method, and unspecified other vectors related to (2) imageop.c, (3) rbgimgmodule.c, and other files, which trigger heap-based buffer overflows.

The bug was discovered 09/16/2007. The weakness was published 09/18/2007 (Website). The advisory is shared for download at us-cert.gov. This vulnerability was named CVE-2007-4965 since 09/18/2007. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Technical details and also a public exploit are known.

A public exploit has been developed in Python. It is possible to download the exploit at securityfocus.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 2 days. During that time the estimated underground price was around $0-$5k.
