Package : nagios3 Version : 3.4.1-3+deb7u3 CVE ID : CVE-2016-9565 CVE-2016-9566

Nagios was found to be vulnerable to two security issues that, when combined, lead to a remote root code execution vulnerability. Fortunately, the hardened permissions of the Debian package limit the effect of those to information disclosure, but privilege escalation to root is still possible locally.


Improper sanitization of RSS feed input enables unauthenticated
remote read and write of arbitrary files which may lead to remote
code execution if the web root is writable.


Unsafe logfile handling allows unprivileged users to escalate their
privileges to root. In wheezy, this is possible only through the
debug logfile which is disabled by default.

For Debian 7 "Wheezy", these problems have been fixed in version 3.4.1-3+deb7u3.

We recommend that you upgrade your nagios3 packages.
