Description Jan Lieskovsky 2013-07-11 12:59:39 EDT
An user details information exposure flaw was found in the way Nagstamon, Nagios status monitor for desktop, performed automated requests to get information about available updates. Remote attacker could use this flaw to obtain user credentials for server monitored by the desktop status monitor due to their improper (base64 encoding based) encoding in the HTTP request, when the HTTP Basic authentication scheme was used.

Reply from Henry Wahl of nagstamon upstream regarding the fix availability for 0.9.9 version:

For those who want to fix a 0.9.9 package there is an updated version at
https://github.com/HenriWahl/Nagstamon/tree/ .
Anyway it is a better idea to upgrade to 0.9.10.

I'm nagstamon maintainer. Updated version without security hole available in updates-testing repo, for update:

yum --enablerepo=updates-testing update nagstamon

It's actual for Fedora 18 and 19.  I'll update nagstamon to 0.9.10 after updates, that's now in testing, will be pushed to updates stable repo.
