Comment 7 Vincent Danen 2014-06-26 21:47:34 UTC
This issue may affect the version of plone as shipped with EPEL5, however the latest version there is 3.1.6 (and the latest 3.x release is 3.3.5, which was released a year prior to this flaw being discovered).  Given the age of the EPEL5 package and its lack of support, we do not recommend anyone use it.

This issue does affect plone as provided with the conga package on Red Hat Enterprise Linux 5.
