Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200705-07
(Lighttpd: Two Denials of Service)

Robert Jakabosky discovered an infinite loop triggered by a connection
abort when Lighttpd processes carriage return and line feed sequences.
Marcus Rueckert discovered a NULL pointer dereference when a server
running Lighttpd tries to access a file with a mtime of 0.

Impact :

A remote attacker could upload a specially crafted file to the server
or send a specially crafted request and then abort the connection,
possibly resulting in a crash or a Denial of Service by CPU
consumption.

Workaround :

There is no known workaround at this time.
