Descriptions

Heap-based buffer overflow in the parse_packet function in network.c in collectd before 5.4.3 and 5.x before 5.5.2 allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via a crafted network packet.

Desbordamiento de búfer basado en memoria dinámica en la función parse_packet en network.c en collectd en versiones anteriores a 5.4.3 y 5.x en versiones anteriores a 5.5.2 permite a atacantes remotos provocar una denegación de servicio (caída del demonio) o posiblemente ejecutar código arbitrario a través de un paquete de red manipulado.

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.
