Debian Security Advisory

DLA-575-1 collectd -- LTS security update

Date Reported:

30 Jul 2016

Affected Packages:

collectd

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 832507, Bug 832577.
In Mitre's CVE dictionary: CVE-2016-6254.

More information:

Emilien Gaspar discovered that collectd, a statistics collection and monitoring daemon, incorrectly processed incoming network packets. This resulted in a heap overflow, allowing a remote attacker to either cause a DoS via application crash, or potentially execute arbitrary code.

Additionally, security researchers at Columbia University and the University of Virginia discovered that collectd failed to verify a return value during initialization. This meant the daemon could sometimes be started without the desired, secure settings.

For Debian 7 Wheezy, these problems have been fixed in version 5.1.0-3+deb7u1.

We recommend that you upgrade your collectd packages.
