OpenTTD up to 0.4.0 memory corruption

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.

Detailsinfo

A vulnerability, which was classified as critical, has been found in OpenTTD up to 0.4.0. Affected by this issue is some unknown processing. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Multiple format string vulnerabilities in OpenTTD before 0.4.0.1 allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unspecified vectors.

The bug was discovered 08/15/2005. The weakness was presented 09/06/2005 by Alexey Dobriyan (Website). The advisory is shared for download at gentoo.org. This vulnerability is handled as CVE-2005-2763 since 09/01/2005. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available.

It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 21 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 19578 (GLSA-200509-03 : OpenTTD: Format string vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Gentoo Local Security Checks and running in the context l.

Upgrading to version 0.4.0.1 eliminates this vulnerability. A possible mitigation has been published before and not just after the disclosure of the vulnerability.
