Comment 1 Vasyl Kaigorodov 2015-07-16 14:09:31 UTC

Created httpd tracking bugs for this issue:

Affects: fedora-all [bug 1243894]

Comment 2 Fedora Update System 2015-07-21 08:12:18 UTC

httpd-2.4.16-1.fc22 has been pushed to the Fedora 22 stable repository.  If problems still persist, please make note of it in this bug report.

Comment 3 Tomas Hoger 2015-07-29 13:39:08 UTC

This issue was actually fixed in version 2.4.14.  However, as versions 2.4.14 and 2.4.15 were not released, 2.4.16 is the first released upstream version that includes the fix.

Upstream commit:

https://svn.apache.org/viewvc?view=revision&revision=1684525

Upstream also notes that this issue is only relevant for httpd 2.4, which made it possible to define authorization requirements and not only authentication requirements using Require configuration directive.  Therefore, httpd modules that use ap_some_auth_required() may incorrectly assume some request required authentication while only some authorization rule was applied.

As httpd versions in Red Hat Enterprise Linux 6 and earlier are based on older upstream httpd version (2.2 or 2.0), the are not affected by this issue.

Comment 4 Fedora Update System 2015-07-30 00:51:45 UTC

httpd-2.4.16-1.fc21 has been pushed to the Fedora 21 stable repository.  If problems still persist, please make note of it in this bug report.
