"Several local/remote vulnerabilities have been discovered in lighttpd,
a fast webserver with minimal memory footprint.

The Common Vulnerabilities and Exposures project identifies the
following problems :

  - CVE-2008-0983
    lighttpd 1.4.18, and possibly other versions before
    1.5.0, does not properly calculate the size of a file
    descriptor array, which allows remote attackers to cause
    a denial of service (crash) via a large number of
    connections, which triggers an out-of-bounds access. 

  - CVE-2007-3948
    connections.c in lighttpd before 1.4.16 might accept
    more connections than the configured maximum, which
    allows remote attackers to cause a denial of service
    (failed assertion) via a large number of connection
    attempts."
