Comment 3 Carl George 🤠 2025-04-11 04:19:53 UTC
This only affects MuJS before version 1.1.2.

* EPEL 9 has version 1.3.2 and thus is not affected.
* EPEL 8 has version 1.0.9 and thus is affected.

Comment 4 Carl George 🤠 2025-04-11 04:29:28 UTC
I was able to backport the upstream CVE fix to the epel8 branch, please review.
