Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5243 advisory.

Several vulnerabilities were discovered in lighttpd, a fast webserver with minimal memory footprint.
CVE-2022-37797 An invalid HTTP request (websocket handshake) may cause a NULL pointer dereference in the wstunnel module. CVE-2022-41556 A resource leak in mod_fastcgi and mod_scgi could lead to a denial of service after a large number of bad HTTP requests. For the stable distribution (bullseye), these problems have been fixed in version 1.4.59-1+deb11u2. We recommend that you upgrade your lighttpd packages. For the detailed security status of lighttpd please refer to its security tracker page at: https://security- tracker.debian.org/tracker/lighttpd
