Comment 1 Guilherme de Almeida Suckevicz 2023-04-25 16:52:50 UTC 
Created yasm tracking bugs for this issue:

Affects: epel-all [bug 2189616]
Affects: fedora-all [bug 2189617]
Comment 3 Siddhesh Poyarekar 2023-04-25 18:39:09 UTC 
yasm is a standalone program and is not designed to run untrusted code off the internet, so while fuzzed inputs expose real bugs, they do not constitute a security issue.
