A security issue affects these releases of Ubuntu and its derivatives:

Summary:
Several security issues were fixed in lighttpd.
Software Description:
- lighttpd: fast webserver with minimal memory footprint
Details:
It was discovered that lighttpd incorrectly handled certain inputs, which could
result in a stack buffer overflow. A remote attacker could possibly use this
issue to cause a denial of service (DoS). (CVE-2022-22707, CVE-2022-41556)
