Debian DLA-3133-1 : lighttpd - LTS security update

high Nessus Plugin ID 165654

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian 10 host has packages installed that are affected by a vulnerability as referenced in the dla-3133 advisory.

 - In lighttpd 1.4.65, mod_wstunnel does not initialize a handler function pointer if an invalid HTTP request (websocket handshake) is received. It leads to null pointer dereference which crashes the server. It could be used by an external attacker to cause denial of service condition. (CVE-2022-37797)

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

Solution

Upgrade the lighttpd packages.

For Debian 10 buster, this problem has been fixed in version 1.4.53-4+deb10u3.
