Descriptions

Incorrect interaction of the parse_packet() and parse_part_sign_sha256() functions in network.c in collectd 5.7.1 and earlier allows remote attackers to cause a denial of service (infinite loop) of a collectd instance (configured with "SecurityLevel None" and with empty "AuthFile" options) via a crafted UDP packet.

La interacción incorrecta de las funciones parse_packet() y parse_part_sign_sha256() en network.c en collectd 5.7.1 y anteriores permite que atacantes remotos provoquen una denegación de servicio (bucle infinito) de una instancia collectd (configurada con opciones "SecurityLevel None" y con empty "AuthFile") a través de un paquete UDP manipulado.

collectd contains an infinite loop due to how the parse_packet() and parse_part_sign_sha256() functions interact. If an instance of collectd is configured with "SecurityLevel None" and empty "AuthFile" options, an attacker can send crafted UDP packets that trigger the infinite loop, causing a denial of service.
