Description Kurt Seifried 2013-04-30 01:41:43 EDT
+++ This bug was initially created as a clone of Bug #957481 +++

Some potential issues discovered whilst auditing openstack & dependencies for tempfile vulnerabilities.

Warning: nagios-3.4.4-1.el6ost/nagios/html/rss-newsfeed.php

    define('MAGPIE_CACHE_DIR', '/tmp/magpie_cache');

    Magpie RSS cache dir is set to a fixed location in /tmp. The cached RSS 
    content is then used to build html content that could be served to
    an end user.
Comment 3 Kurt Seifried 2013-04-30 14:35:03 EDT
This has been reported upstream: http://tracker.nagios.org/view.php?id=450
Comment 4 Kurt Seifried 2013-08-07 21:48:17 EDT
Created nagios tracking bugs for this issue:

Affects: fedora-all [bug 994779]
Affects: epel-6 [bug 994780]
Comment 5 Lon Hohberger 2013-10-23 15:59:38 EDT
This is not fixed by nagios 3.5.1.
Comment 6 Lon Hohberger 2013-10-23 17:49:21 EDT
define('MAGPIE_DIR', './includes/rss/');
define('MAGPIE_CACHE_ON', 0);
define('MAGPIE_CACHE_AGE', 0);
define('MAGPIE_CACHE_DIR', '/tmp/magpie_cache');

Defining MAGPIE_CACHE_ON to 1 is required in order for MAGPIE_CACHE_DIR to be used.

rss_newsfeed.php disables the cache, so this directory is not used without editing the PHP code (note: *not* a configuration file).

As it is unused without editing the rss-newsfeed.php file, I will simply comment the line out *and* replace it with a usage comment.
Comment 7 Martin Prpič 2013-11-14 12:02:58 EST
