Sorry to resurrect this thread. Another issue - which is not per-se a security issue but it's still a problem - is that deltarpm uses md5 checksums pervasively. They're everywhere. And it uses its own implementation of md5 which doesn't respect FIPS, so even when the user has *explicitly* configured their system to not use md5 for anything security-relevant, libdeltarpm won't know or care. _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
