- Details

A resource leak in gwbackend.c in lighttpd 1.4.56 through 1.4.66 could lead to a denial of service (connection-slot exhaustion) after a large amount of anomalous TCP behavior by clients. It is related to RDHUP mishandling in certain HTTP/1.1 chunked situations. Use of modfastcgi is, for example, affected. This is fixed in 1.4.67.
