Comment 3 Andrea Mattiazzo 2024-01-04 10:17:03 UTC 
As agreed, closed as wontfix
Comment 4 Andrea Mattiazzo 2024-01-04 11:05:17 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.
