its easy to inject code to the script e.g. via model name or pdl key
which is taken from the LAN packets.
This issue was reported as fixed in 1.0.51:
but it was found that the fix was incomplete with the full fix in 1.0.53:
Should this get a second CVE or should we continue to use CVE-2014-2707?
Furthermore, another security issue was also fixed in 1.0.53:
- 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 (Bug #1204).
I believe this should receive a CVE.
