In lighttpd 1.4.46 through 1.4.63, the mod_extforward_Forwarded function of the mod_extforward plugin has a stack-based buffer overflow (4 bytes representing -1), as demonstrated by remote denial of service (daemon crash) in a non-default configuration. The non-default configuration requires handling of the Forwarded header in a somewhat unusual manner. Also, a 32-bit system is much more likely to be affected than a 64-bit system.

The remote Ubuntu 20.04 LTS / 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5903-1 advisory.

    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)
