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 problematic has been found in IBM AIX (Operating System) (unknown version). Affected is an unknown code block of the component Diagnostics Library. The manipulation of the argument DIAGNOSTICS as part of a Environment Variable leads to a memory corruption vulnerability. CWE is classifying the issue as 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. This is going to have an impact on integrity. CVE summarizes:

Buffer overflow in the diagnostics library in AIX allows local users to "cause data and instructions to be overwritten" via a long DIAGNOSTICS environment variable.

The weakness was disclosed 12/31/2002 (Website). The advisory is shared for download at archives.neohapsis.com. This vulnerability is traded as CVE-2002-1687 since 06/21/2005.
