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 the stable distribution (jessie), this problem has been fixed in version 5.4.1-6+deb8u1. For the testing (stretch) and unstable (sid) distributions, this problem has been fixed in version 5.5.2-1. We recommend that you upgrade your collectd packages.
