Simon Tatham NASM up to 0.98.39 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.

Detailsinfo

A vulnerability was found in Simon Tatham NASM up to 0.98.39 (Programming Tool Software). It has been classified as critical. Affected is an unknown code block. The manipulation with an unknown input leads to a stack-based overflow vulnerability. CWE is classifying the issue as 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). This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Stack-based buffer overflow in the ieee_putascii function for nasm 0.98 and earlier allows attackers to execute arbitrary code via a crafted asm file, a different vulnerability than CVE-2004-1287.

The bug was discovered 05/17/2005. The weakness was disclosed 05/18/2005 by Jindrich Novy (Website). The advisory is available at sourceforge.net. This vulnerability is traded as CVE-2005-1194 since 04/21/2005. Access to the local network is required for this attack. The exploitation doesn't require any form of authentication. The technical details are unknown and an exploit is not available.

The vulnerability scanner Nessus provides a plugin with the ID 18306 (Mandrake Linux Security Advisory : nasm (MDKSA-2005:090)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Mandriva Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 117925 (CentOS Security Update for NASM (CESA-2005:381)).
