Description

The affected mod_lua module was introduced upstream in version 2.4: http://httpd.apache.org/docs/2.4/new_features_2_4.html#newmods Therefore, this issue did not affect httpd versions as shipped in Red Hat Enterprise Linux 6 and earlier, which include httpd 2.2 or earlier. Upstream commits in trunk and 2.4.x branch: https://svn.apache.org/viewvc?view=revision&revision=1657261 https://svn.apache.org/viewvc?view=revision&revision=1664118 This is apparently planned to be fixed in not yet released 2.4.13. This issue does not affect the version of httpd package as shipped with Red Hat Enterprise Linux 7, because mod_lua in that package does not have WebSocket support. Created httpd tracking bugs for this issue: Affects: fedora-all [bug 1232127] Statement: This issue did not affect the version of httpd package as shipped with Red Hat Enterprise Linux 5, 6 and 7. 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. (In reply to Tomas Hoger from comment #3) > This is apparently planned to be fixed in not yet released 2.4.13. This was fixed in 2.4.13, but that version, along with version 2.4.14 and 2.4.15 were never released. The first released version with the fix is 2.4.16.

Sidhpurwala from comment #4) > This issue does not affect the version of httpd package as shipped with Red > Hat Enterprise Linux 7, because mod_lua in that package does not have > WebSocket support. Upstream security page linked in comment 8 clarifies that the vulnerable code was introduced in upstream version 2.4.7. The httpd packages in Red Hat Enterprise Linux 7 are based on older upstream version 2.4.6. httpd-2.4.16-1.fc21 has been pushed to the Fedora 21 stable repository.
