Description Murray McAllister 2014-07-25 04:29:31 UTC 
The upstream Bugzilla 4.0.14, 4.2.10, 4.4.5, 4.5.5 releases fix the following issue:

""
Adobe does not properly restrict the SWF file format,
which allows remote attackers to conduct cross-site
request forgery (CSRF) attacks against Bugzilla's JSONP
endpoint, possibly obtaining sensitive bug information,
via a crafted OBJECT element with SWF content satisfying
the character-set requirements of a callback API.

References:  https://bugzilla.mozilla.org/show_bug.cgi?id=1036213
""

The 3.2.10 and 3.4.14 versions in EPEL 5 and 6 appear too old to be affected.

Comment 1 Murray McAllister 2014-07-25 04:30:38 UTC 
Created bugzilla tracking bugs for this issue:

Affects: fedora-all [bug 1123173]
Comment 2 Tomas Hoger 2014-07-25 06:48:48 UTC 
Note that the issue was fixed in Adobe Flash, see CVE-2014-4671 (bug 1117588).  The fix in Flash should address the issue, with Bugzilla fix only providing protection to users running outdated Flash.

Details of the attack are in the following blog post:
