Description Vincent Danen 2014-04-25 23:11:45 UTC 
A flaw in cups-filters was fixed upstream [1] and is described as follows:

cups-browsed: SECURITY FIX: Fix on usage of the "BrowseAllow" directive in cups-browsed.conf. Before, if the argument of a "BrowseAllow" directive is not understood it is treated as the directive not having been there, allowing any host if this was the only "BrowseAllow" directive. Now we treat this as a directive which no host can fulfill, not allowing any host if it was the only one. No "BrowseAllow" directive means access for all, as before ([2]).
