"The remote Ubuntu 22.04 LTS / 24.04 LTS / 25.10 / 26.04 LTS host has packages installed that are affected by multiple
vulnerabilities as referenced in the USN-8354-1 advisory.

    It was discovered that nginx did not properly validate source addresses in the HTTP/3 QUIC module. A
    remote attacker could possibly use this issue to bypass authorization checks or rate limiting. This issue
    only affected Ubuntu 25.04 and Ubuntu 25.10. (CVE-2026-40460)

    It was discovered that nginx contained a use-after-free vulnerability in the ngx_http_ssl_module module
    when client certificate verification and OCSP validation were enabled. A remote attacker could use this
    issue to cause nginx to crash, resulting in a denial of service, or possibly modify data in memory.
    (CVE-2026-40701)

    It was discovered that nginx did not properly handle certain proxied responses in the
    ngx_http_charset_module module. A remote attacker could possibly use this issue to obtain sensitive
    information or cause nginx to crash, resulting in a denial of service. (CVE-2026-42934)

    It was discovered that nginx did not properly process certain SCGI and uWSGI responses. An attacker able
    to perform a machine-in-the-middle attack could possibly use this issue to obtain sensitive information or
    cause nginx to crash, resulting in a denial of service. (CVE-2026-42946)

    It was discovered that nginx incorrectly handled certain rewrite rules in the ngx_http_rewrite_module
    module. A remote attacker could use this issue to cause nginx to crash, resulting in a denial of service,
    or possibly execute arbitrary code. (CVE-2026-9256)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
