lighttpd: Multiple vulnerabilities

lighttpd: Multiple vulnerabilities Multiple vulnerabilities in lighttpd may lead to information disclosure or a Denial of Service. lighttpd December 02, 2008 December 02, 2008: 01 238180 remote 1.4.20 1.4.20

lighttpd is a lightweight high-performance web server.

Multiple vulnerabilities have been reported in lighttpd:

Qhy reported a memory leak in the http_request_parse() function in request.c (CVE-2008-4298).
Gaetan Bisson reported that URIs are not decoded before applying url.redirect and url.rewrite rules (CVE-2008-4359).
Anders1 reported that mod_userdir performs case-sensitive comparisons on filename components in configuration options, which is insufficient when case-insensitive filesystems are used (CVE-2008-4360).

A remote attacker could exploit these vulnerabilities to cause a Denial of Service, to bypass intended access restrictions, to obtain sensitive information, or to possibly modify data.

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-1.4.20"
