Fedora has issued an advisory for this on April 18:
https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/thread/R7LKQDFZWKYHQ65TBSH2X2HJQ4V2THS3/

Apparently they had backported the introduction of the issue to 8.8p1 so they had to backport the fix.  Hopefully we haven't also done the former.

We have version 8.4p1 in Mageia 8, and I can't find any trace of the offending code, so I think it's safe to assume we're not affected.
