Summary
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.
