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.
This issue was actually fixed in version 2.4.13. However, as versions 2.4.13, 2.4.14 and 2.4.15 were not released, 2.4.16 is the first released upstream version that includes the fix. Upstream bug report for this issue: https://bz.apache.org/bugzilla/show_bug.cgi?id=57531 Upstream commit (in 2.4.x branch) fixing the problem: https://svn.apache.org/viewvc?view=revision&revision=1668879 Upstream notes that the issue only affected version starting with 2.4.11, which includes the following fix: *) core: Support custom ErrorDocuments for HTTP 501 and 414 status codes. PR 57167 [Edward Lu <Chaosed0 gmail.com>] Upstream bug report: https://bz.apache.org/bugzilla/show_bug.cgi?id=57167 Upstream commit (in 2.4.x branch): https://svn.apache.org/viewvc?view=revision&revision=1638071 This adds an ap_die() call to ap_read_request(), which eventually leads to the NULL pointer dereference issue for which CVE-2015-0253 was assigned. The above change is not include in Red Hat Enterprise Linux 7 and earlier httpd packages, therefore they are not affected by this issue. This issue causes httpd child process crash. When using prefork MPM, such crash only affects attacker's connection. For other MPMs, connections of other users may be affected.
Statement: This issue did not affect the versions of httpd as shipped with Red Hat Enterprise Linux 4, 5, 6, and 7; JBoss Enterprise Web Server 1 and 2; JBoss Web Server 3; and JBoss Enterprise Application Platform 6.
