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 of problem:
Hi python maintainers,
I plan to fix blocker CVE in expat library for RHEL 9. This fix
makes expat parsing more strict and breaks pythons testsuite.
https://github.com/python/cpython/commit/2cae93832f46b245847bdc252456ddf7742ef45e

This commit fixes the issue.

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


How reproducible:
Try to compile python with this https://kojihub.stream.rdu2.redhat.com/koji/taskinfo?taskID=1022352 version of expat library.

Actual results:
Testsuite failure

Expected results:
Testsuite finishes successfully.

Feel free to not block the CVE fix on this.

Hey Tomas,

Thanks for notifying us!

Do you plan to backport the fix or rebase?

Asking as the upstream python test suite fix is checking for the version string coming from pyexpat.version_info to determine the proper tests to run.

The expat component has been rebased, therefore we no longer need a downstream patch for python3 after we rebase to the latest python 3.9 version.

Next action: Rebase Python 3.9 in RHEL 9 to the latest version.

Since the problem described in this bug report should be
resolved in a recent advisory, it has been closed with a
resolution of ERRATA.

For information on the advisory (Moderate: python3.9 security, bug fix, and enhancement update), and where to find the updated
files, follow the link below.

If the solution does not work for you, open a new bug report.
