Tracking as affected:
- SUSE:ALP:Source:Standard:1.0/yasm  1.3.0
- SUSE:SLE-12:Update/yasm            1.2.0
- SUSE:SLE-15:Update/yasm            1.3.0
- openSUSE:Factory/yasm              1.3.0

Closed as wontfix due to the nature of the bug and 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.
