Red Hat Bugzilla is now running version 4.4.4019-2. This introduces the following authentication error when using Eclipse Mylyn : "untrusted authentication request: You tried to log in using the $EMAIL account, but $BUGZILLA_NAME is unable to trust your request. Make sure your web browser accepts cookies and that you haven't been redirected here from an external web site.Click here if you really want to log in." This has been fixed upstream at https://bugs.eclipse.org/bugs/show_bug.cgi?id=433095 with http://git.eclipse.org/c/mylyn/org.eclipse.mylyn.tasks.git/commit/?id=0b7e999d7f580408625d23596533327de4b8ce20 . In particular this provides a fix for CVE-2014-1517. Note that rawhide (f21) will simply ship Eclipse Mylyn's Luna (4.4) contribution and its pre-releases which should have the fix anyways.
