Description Jan Lieskovsky 2011-11-30 09:38:14 UTC
An signedness error, leading to out of stack-based buffer read flaw was found in the way lighttpd, a lightning fast webserver with light system requirements, processed certain invalid base64 HTTP authentication tokens. A remote attacker could provide a specially crafted HTTP authentication request, leading to denial of service (lighttpd daemon crash due to an signedness error while processing the token).
