Description Jan Lieskovsky 2012-11-12 19:23:18 UTC 
A privilege escalation flaw was found in the way cups, a Common Unix Printing System, performed demarcation of privileges for the members of SystemGroup, different from the privileged-user account (root). A remote attacker, member of some of the CUPS SystemGroup groups, could use this flaw to read / write arbitrary system file with the privileges of the user running the CUPS daemon.
