For the remaining issues, that got fixed in MediaWiki 1.20.1, MediaWiki 1.19.3 and MediaWiki 1.18.6, exactly: * A similar vulnerability was also identified in the CentralAuth Extension, and assigned CVE-2012-5395.

Created mediawiki tracking bugs for this issue Affects: fedora-all [bug 882344] Affects: epel-5 [bug 882345] I will apply the upstream patch to the Fedora and EPEL repos. Also impacted: mediawiki119 package for EPEL 6 (In reply to comment #6) > Also impacted: mediawiki119 package for EPEL 6 This is correct. Thank you for pointing out (mediawiki116 should be included in the list too). Will do shortly. Created mediawiki116 tracking bugs for this issue Affects: epel-all [bug 885016] mediawiki-1.19.4-2.fc17 has been pushed to the Fedora 17 stable repository. If problems still persist, please make note of it in this bug report. mediawiki-1.19.4-2.fc18 has been pushed to the Fedora 18 stable repository. If problems still persist, please make note of it in this bug report. As noted in the mediawiki119 tracking bug, this has also been fixed for that one as well. The EPEL5 version is the only one not yet closed, because that branch is orphaned. |
