Original description

gitoxide gix-pack before 0.75.0 contains a reachable assertion in BytesToEntriesIter::new_from_header: the pack header decoder accepts version 3, but a release-enabled assert_eq! requires version 2. A malicious remote can send a 12-byte pack header declaring version 3 to panic the client and abort the clone or fetch.
