lighttpd is a small-footprint, fast, compliant and very flexible
|
|
web-server which is optimized for high-performance environments.

<p>
|
|
lighttpd uses file extensions to determine which elements are programs
|
|
that should be executed and which are static pages that should be sent
|
|
as-is. By appending %00 to the filename, you can evade the extension
|
|
detection mechanism while still accessing the file.

|
|
A remote attacker could send specific queries and access the source of
|
|
scripts that should have been executed as CGI or FastCGI applications.

<workaround>

There is no known workaround at this time.

All lighttpd users should upgrade to the latest version:

<code>
|

# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=www-servers/lighttpd-1.3.10-r1"</code>
