lighttpd < 1.4.26 or 1.5.0 Denial of Service

medium Nessus Plugin ID 106625

Synopsis

The remote web server is affected by a denial of service vulnerability

Description

According to its banner, the version of lighttpd running on the remote host is prior to 1.4.26 or is 1.5.0. It is, therefore, affected by the following vulnerabilities :

 - lighttpd allocates a buffer for each read operation which allows remote attackers to cause a denial of service (memory consumption) by breaking a request into small pieces that are sent at a slow rate.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to lighttpd version 1.4.26. Alternatively, apply the vendor-supplied patch.
