1525636 – unzip doesn't properly extract Deflate64 files on RHEL7

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Chris Cheney 2017-12-13 18:51:06 UTC

Created attachment 1367521 [details]
Example bad CRCs with Deflate64 on RHEL7

Description of problem:

On RHEL7 unzip doesn't properly extract files compressed with Deflate64 (PKZIP version 2.1). It works fine on RHEL6. I looked through the patches but wasn't able to determine what was different that caused the problem.


Version-Release number of selected component (if applicable):

unzip-6.0-5.el6.x86_64 - good

unzip-6.0-16.el7.x86_64 - bad


How reproducible:

Use PKZIP to create an archive using Deflate64 compression. Info-Zip 'zip' in RHEL appears to not support Deflate64 for compression. I have attached an example archive.


Actual results:

RHEL7

unzip -t -v test-file.zip 
Archive:  test-file.zip
    testing: test-file.1              OK
    testing: test-file.10             bad CRC 33116a89  (should be b9f107df)
