[Bug 1830629] Re: Errors when extracting ZIP files. It can not differentiate between files and directories

[Sebastien Bacher]

Thank you for your bug report, marking the bug as fixed since the issue
is resolved in the current version.

We are doing a SRU backport to Bionic as well (the corresponding line
will be added to the report)

** Changed in: libarchive (Ubuntu)
   Importance: Undecided => High

** Changed in: libarchive (Ubuntu)
       Status: New => Fix Released

** Description changed:

- The specific version included in Ubuntu 18.04 (libarchive 3.2.2) is the
- only version that presents the problem. This version has a known problem
- when reading file entries in ZIP files, where it incorrectly identifies
- directories and files entries.
+ * 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.
