lighttpd < 1.4.30 base64_decode Function Out-of-Bounds Read Error DoS

medium Nessus Plugin ID 57410

Language:

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 1.4.30. It is, therefore, affected by a denial of service vulnerability. The HTTP server allows out-of-bounds values to be decoded during the auth process and later uses these values as offsets. Using negative values as offsets can result in application crashes.

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

Solution

Upgrade to lighttpd version 1.4.30 or later. Alternatively, apply the vendor-supplied patch or disable mod_auth.
