Description

Several local/remote vulnerabilities have been discovered in lighttpd, a fast webserver with minimal memory footprint.

The Common Vulnerabilities and Exposures project identifies the following problems :

  • CVE-2008-4298 A memory leak in the http_request_parse function could be used by remote attackers to cause lighttpd to consume memory, and cause a denial of service attack.

  • CVE-2008-4359 Inconsistant handling of URL patterns could lead to the disclosure of resources a server administrator did not anticipate when using rewritten URLs.

  • CVE-2008-4360 Upon filesystems which don't handle case-insensitive paths differently it might be possible that unanticipated resources could be made available by mod_userdir.
