NixOS vulnerability analysis and mitigation
Overview
CVE-2023-29583 is a stack overflow vulnerability discovered in yasm version 1.3.0.55.g101bc. The vulnerability exists in the parse_expr5 function located in /nasm/nasm-parse.c. This issue has been disputed by third parties who argue that it is a bug rather than a security issue, since yasm is a standalone program not designed to run untrusted code (NVD).
Technical details
The vulnerability manifests as a stack overflow condition in the parse_expr5 function within the NASM parser component. The issue occurs during expression parsing and can be triggered through recursive function calls. The vulnerability has been assigned a CVSS v3.1 base score of 5.5 (MEDIUM) with vector CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H by NIST, and a score of 6.2 (MEDIUM) by CISA-ADP (NVD).
Impact
When exploited, the vulnerability can cause a stack overflow condition leading to program termination. The impact is primarily on availability, with no direct impact on confidentiality or integrity. However, since this is a standalone program for assembly processing, the real-world impact is limited (NVD).
