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.

"ported" patch

Description of problem:

URL: http://svn.apache.org/viewvc?rev=1708699&view=rev

The fix for CVE-2015-3184 (Subversion) and CVE-2015-3185 (httpd) broke
the use of 3rd party modules such as mod_auth_kerb and mod_auth_ntlm
when mandatory authn was combined with mod_authz_svn.  The problem
was httpd returned a 401 response without an Authentication header
meaning the client was unable to authenticate.  By returning DECLINED
we allow the authn module to generate a 401 with the correct headers.

Version-Release number of selected component (if applicable):
subversion-1.7.14-10

How reproducible:
Always

Steps to Reproduce:
Set up an SVN repository and HTTP server with Kerberos authentication. See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=799105 for a sample config reproducer. Without the patch, you would get an unauthorized error. With the patch, you should get authenticated.
