Debian: New lighttpd packages fix several vulnerabilities

Several vulnerabilities were discovered in lighttpd, a fast webserver with minimal memory footprint. The use of mod_auth could leave to a denial of service attack crashing the webserver The improper handling of repeated HTTP headers could cause a denial of serve attack crashing the webserver. A bug in mod_access potentially allows remote users to bypass access restrictions via trailing slash characters. On 32-bit platforms users may be able to create denial of service attacks, crashing the webserver, via mod_webdav, mod_fastcgi, or mod_scgi. Fixed packages are available from security.debian.org.
