Title:
  Errors when extracting ZIP files. It can not differentiate between
  files and directories

Status in libarchive package in Ubuntu:
  Fix Released
Status in libarchive source package in Bionic:
  Fix Committed

Bug description:
  * Impact
  The bionic version has a known problem when reading file entries in ZIP files, where it incorrectly identifies directories and files entries.

  * Test case
  $ wget https://bugs.launchpad.net/ubuntu/+source/libarchive/+bug/1830629/+attachment/5268728/+files/example.zip
  $ bsdtar -vxf example.zip
  $ ls -l

  The 'ABCD_1234' and 'empty' entries should be directories

  * Regression potential
  Check that extracting zips from bsdtar or nautilus work without issue

  --------------------------------

  It has been confirmed that the previous and following versions
  (3.3.1+) do not have this problem and the library handles the ZIP
  files correctly.

  Is it possible to include a newer version of libarchive (3.3.1+) in
  Bionic?

  This problem is seriously affecting some of our systems.
