Comment 3 Nick Clifton 2024-01-16 11:45:23 UTC
I have filed a dispute for this CVE based upon the fact that it does not meet the criteria for a security vulnerability as established by the yasm project's security.md file:

https://redhat.service-now.com/help?id=rh_ticket&table=incident&sys_id=91e8cf21db6b759433c345e8139619c6

Please could ProdSec respond ?
