lighttpd is a lightweight high-performance web server.
Li Ming reported that lighttpd does not properly process packets that are sent overly slow.
A remote attacker might send specially crafted packets to a server running lighttpd, possibly resulting in a Denial of Service condition via host memory exhaustion.
There is no known workaround at this time.
All lighttpd users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-servers/lighttpd-1.4.25-r1"
