Description Guilherme de Almeida Suckevicz 2020-07-28 17:07:40 UTC 
Cherokee 0.4.27 to 1.2.104 is affected by a denial of service due to a NULL pointer dereferences. A remote unauthenticated attacker can crash the server by sending an HTTP request to protected resources using a malformed Authorization header that is mishandled during a cherokee_buffer_add call within cherokee_validator_parse_basic or cherokee_validator_parse_digest.
