GLSA-200708-11 : Lighttpd: Multiple vulnerabilities

This script is Copyright (C) 2007-2014 Tenable Network Security, Inc.


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-200708-11
(Lighttpd: Multiple vulnerabilities)

Stefan Esser discovered errors with evidence of memory corruption in
the code parsing the headers. Several independent researchers also
reported errors involving the handling of HTTP headers, the mod_auth
and mod_scgi modules, and the limitation of active connections.

Impact :

A remote attacker can trigger any of these vulnerabilities by sending
malicious data to the server, which may lead to a crash or memory
exhaustion, and potentially the execution of arbitrary code.
Additionally, access-deny settings can be evaded by appending a final /
to a URL.

Workaround :

There is no known workaround at this time.

Solution :

All Lighttpd users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=www-servers/lighttpd-1.4.16'

Risk factor :

High / CVSS Base Score : 8.3
