GLSA-200502-21 : lighttpd: Script source disclosure

This script is Copyright (C) 2005-2015 Tenable Network Security, Inc.

Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-200502-21
(lighttpd: Script source disclosure)

lighttpd uses file extensions to determine which elements are programs
that should be executed and which are static pages that should be sent
as-is. By appending %00 to the filename, you can evade the extension
detection mechanism while still accessing the file.

Impact :

A remote attacker could send specific queries and access the source of
scripts that should have been executed as CGI or FastCGI applications.

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-1.3.10-r1'

Risk factor :

Medium / CVSS Base Score : 5.0
