As agreed, closed as wontfix

Comment 4 Andrea Mattiazzo 2024-01-04 11:05:13 UTC

Just to add more info, closed as wontfix due to the context of yasm tool: an attacker could directly insert malicious code in the input file, there is no additional value gathered from exploiting the vulnerability creating an ad-hoc input file.
