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.

For the stable distribution (etch), these problems have been fixed in version 1.4.13-4etch11.

For the unstable distribution (sid), these problems will be fixed shortly.

We recommend that you upgrade your lighttpd package.");
