Lighttpd 1.4.56 through 1.4.58 allows a remote attacker to cause a denial of service (CPU consumption from stuck connections) because connection_read_header_more in connections.c has a typo that disrupts use of multiple read operations on large headers.
The product performs a calculation that generates incorrect or unintended results that are later used in security-critical decisions or resource management.
