"The update for monit issued as DLA-732-1 causes monit to segfault when
using the collector function meant to provide data to M/Monit. This
update fixes the regression. For reference the original advisory text
follows.

Adith Sudhakar discovered a cross-site request forgery (CSRF) issue in
monit, a utility for monitoring hosts and services. An attacker could
cause an authenticated admin to change monitoring for hosts/services
through a forged link. This update fixes the vulnerability by adding
CSRF protection via a security token and enforced POST requests for
actions that cause changes to the monitoring.

For Debian 7 'Wheezy', these problems have been fixed in version
1:5.4-2+deb7u3.

We recommend that you upgrade your monit packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.");
