Description Tomas Hoger 2008-10-06 08:44:20 UTC

Common Vulnerabilities and Exposures assigned an identifier CVE-2008-4359 to the following vulnerability:

lighttpd before 1.4.20 compares URIs to patterns in the (1) url.redirect and
(2) url.rewrite configuration settings before performing URL decoding, which
might allow remote attackers to bypass intended access restrictions, and obtain
sensitive information or possibly modify data.

Affected versions:
all versions before 1.4.20 (1.5 before r2310)

Rawhide version lighttpd-1.4.20-0.1.r2303.fc10 contains mod_rewrite part of the fix, but is missing mod_redirect part.
