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.
