Hi,
The file html/rss-newsfeed.php in nagios3 (installed into nagios3-cgi)
use /tmp insecurely by fixed cache dir name:
Actually, besides the tempfile usage, this PHP script exists to query the
Nagios upstream website on any load of the front page of the installation,
which leaks information about machines having Nagios installed. Perhaps
it's better to just remove this functionality.
I've refactored an old patch against the 3.4.1 release which Debian uses
in order to remove that "feature" entirely. It still leaves the php
requirement intact - re-establishing the old html style will make the
patch likely incompatible to upstream.

Note: Also applies against 4.x HEAD.
Furthermore, I've ported a core patch I've implemented for Icinga years
ago, which entirely removes the core's "feature" to schedule daily timed
events for update checks. Upstream allows you to disable those checks
via config option, but it still causes some noops for the unused
functionality. Based on 3.4.1 for Debian too.

Note: Does not apply against 4.x HEAD, there have been too many changes.
A compatible patch is located here:
