"Several vulnerabilities were discovered in lighttpd, a fast webserver
with minimal memory footprint, which could allow the execution of
arbitrary code via the overflow of CGI variables when mod_fcgi was
enabled. The Common Vulnerabilities and Exposures project identifies
the following problems :

  - CVE-2007-3946
    The use of mod_auth could leave to a denial of service
    attack crashing the webserver.

  - CVE-2007-3947
    The improper handling of repeated HTTP headers could
    cause a denial of service attack crashing the webserver.

  - CVE-2007-3949
    A bug in mod_access potentially allows remote users to
    bypass access restrictions via trailing slash
    characters.

  - CVE-2007-3950
    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."
