The original fix introduces regressions when extracting certain lbzip2 files
which were created with a buggy libzip2: https://bugs.debian.org/931278
Details on followup: https://sourceware.org/ml/bzip2-devel/2019-q3/msg00007.html
explaining as well why, whilst the issue described by CVE-2019-12900 is definitvely
an issue, it was not exploitable in the first place.
