Description Agostino Sarubbo gentoo-dev 2013-01-04 19:19:04 UTC
From $URL :

During the process of CUPS socket activation code refactoring in favour of systemd capability a 
security flaw was found in the way CUPS service honoured Listen localhost:631 cupsd.conf 
configuration option. 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.

printing: Fedora's fix [1] was to drop the IP socket activation

@systemd: please help, because I dont really know what this is about
Comment 3 Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2013-06-06 17:24:11 UTC
I don't understand it either. There's a problem with IPv6, so Fedora disabled IPv4? ;f
Comment 4 Andreas K. Hüttel gentoo-dev 2013-06-26 22:56:53 UTC
This is not a regression in 1.6

this bug report is so old now, but i still get this error with

net-print/cups-2.0.0-r2 and systemd 

so there is a solution insight?

Package is now stable, but not vulnerable.  Leaving original whiteboard values in place.
