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.

Resolution Information
Workaround
There is no known workaround at this time.
