Missing Release of Resource after Effective Lifetime vulnerability in Erlang/OTP inets httpd allows an unauthenticated remote attacker to cause denial of service by sending a request with a chunked body whose chunk-size line is not a hexadecimal number. The worker serving the connection is never released and no timeout reclaims it, so repeating the request across connections occupies every available worker and denies service to legitimate clients. No authentication is required and the default configuration is affected. The chunk-size line must arrive in a write separate from the headers. When the body accompanies the headers, httpdrequesthandler:handlebody/3 calls httpchunk:decode/3 inside a try ... catch throw:Error, so the {error, {chunksize, }} thrown by httpchunk:decodesize/4 is answered with 400 Bad Request. When the chunk size arrives later, the decoder is resumed through a bare catch in httpdrequesthandler:handleinfo/2, which converts the throw into a return value rather than raising it; the resulting error tuple is then treated as the next decoder continuation, the socket is re-armed, and the worker waits for data that never comes. The request timeout has already been…
