Overview
CVE-2023-31974 is a use-after-free vulnerability discovered in YASM version 1.3.0. The vulnerability specifically affects the error function in the /nasm/nasm-pp.c file. This issue was initially reported on May 9, 2023, though it's worth noting that multiple third parties have disputed this as a bug rather than a vulnerability according to the YASM security policy (NVD).
Technical details
The vulnerability has been assigned a CVSS v3.1 Base Score of 5.5 (Medium) with the vector string CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H. The issue is classified as CWE-416 (Use After Free). The vulnerability can be triggered through specific command-line parameters, specifically when using the -w and -W flags with the -M option (GitHub Issue).
Impact
The vulnerability affects the availability of the system, as indicated by the CVSS metrics showing high impact on availability (A:H) but no impact on confidentiality (C:N) or integrity (I:N). The local nature of the attack (AV:L) and the requirement for user interaction (UI:R) somewhat limit the potential impact (NVD).
