Synopsis

Multiple vulnerabilities in lighttpd may lead to information disclosure or a Denial of Service.

2.  Impact Information

Background

lighttpd is a lightweight high-performance web server.

Description

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).

Impact

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.

3.  Resolution Information

Workaround

There is no known workaround at this time.

Resolution

All lighttpd users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=www-servers/lighttpd-1.4.20"
