The setting was recognized properly for IPv4-enabled systems, but failed to be correctly applied for IPv6-enabled systems. As a result, a remote attacker could use this flaw to obtain (unauthorized) access to the CUPS web-based administration interface. References:  https://bugzilla.novell.com/show_bug.cgi?id=795624  https://bugzilla.redhat.com/show_bug.cgi?id=891942 Note: Obviously this would affect only instances, where CUPS was instructed to pass its socket activation code to systemd (instances not using systemd would not be affected by this problem). Could you allocate a CVE identifier for this? Thank you && Regards, Jan. -- Jan iankko Lieskovsky / Red Hat Security Response Team
