Description OSIDB Bzimport 2026-04-10 14:01:34 UTC 
A heap buffer overflow vulnerability exists in the Netwide Assembler (NASM) due to a lack of bounds checking in the obj_directive() function. This vulnerability can be exploited by a user assembling a malicious .asm file, potentially leading to heap memory corruption, denial of service (crash), and arbitrary code execution.
Comment 3 Dominik 'Rathann' Mierzejewski 2026-04-22 20:55:10 UTC 
CVSS score at NVD is wrong, should be 5.5 medium. (AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H)
