Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 35 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2022-c26b19568d advisory.

 - A resource leak in gw_backend.c in lighttpd 1.4.56 through 1.4.66 could lead to a denial of service (connection-slot exhaustion) after a large amount of anomalous TCP behavior by clients. It is related to RDHUP mishandling in certain HTTP/1.1 chunked situations. Use of mod_fastcgi is, for example, affected.
 This is fixed in 1.4.67. (CVE-2022-41556)

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

Solution

Update the affected lighttpd package.
