Detailsinfo

A vulnerability was found in NetBSD up to 1.6 (Operating System). It has been rated as problematic. Affected by this issue is an unknown function of the component xterm. 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:

Buffer overflow in setlocale in libc on NetBSD 1.4.x through 1.6, and possibly other operating systems, when called with the LC_ALL category, allows local attackers to execute arbitrary code via a user-controlled locale string that has more than 6 elements, which exceeds the boundaries of the new_categories category array, as exploitable through programs such as xterm and zsh.

The weakness was shared 09/17/2002 (Website). The advisory is shared for download at ftp.netbsd.org. This vulnerability is handled as CVE-2002-1476. The exploitation is known to be easy. The attack needs to be approached locally. No form of authentication is required for exploitation. Technical details are unknown but an exploit is available.
