"The remote Ubuntu 22.04 LTS / 24.04 LTS / 26.04 LTS / 26.10 host has packages installed that are affected by multiple
vulnerabilities as referenced in the USN-8955-1 advisory.

    It was discovered that nginx incorrectly handled certain configurations using the alias directive together
    with rewrite rules. A remote attacker could possibly use this issue to cause nginx to crash, resulting in
    a denial of service, or execute arbitrary code. (CVE-2026-15176)

    It was discovered that nginx incorrectly handled map directives using regex matching under certain
    circumstances. A remote attacker could possibly use this issue to cause nginx to crash, resulting in a
    denial of service, or execute arbitrary code. (CVE-2026-93479)

    It was discovered that nginx incorrectly handled HTTP/3 requests when proxy_request_buffering was enabled.
    This issue only affected Ubuntu 26.04 LTS and Ubuntu 26.10. A remote attacker could possibly use this
    issue to inject data into proxied requests. (CVE-2026-95101)

    It was discovered that nginx incorrectly handled asynchronous file I/O in certain configurations with
    Server Side Includes pages. A remote attacker could possibly use this issue to cause nginx to crash,
    resulting in a denial of service, or execute arbitrary code. (CVE-2026-97205)

    It was discovered that nginx incorrectly handled SSL session ticket keys when configured with a shared
    session cache but without explicit ticket key rotation. This issue only affected Ubuntu 24.04 LTS, Ubuntu
    26.04 LTS, and Ubuntu 26.10. A remote attacker could possibly use this issue to forge client SSL sessions
    and bypass client certificate verification. (CVE-2026-97629)

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
