"The remote Ubuntu 22.04 LTS / 24.04 LTS host has a package installed that is affected by multiple vulnerabilities as
referenced in the USN-8089-1 advisory.

    Bahruz Jabiyev, Tommaso Innocenti, Anthony Gavazzi, Steven Sprecher, and Kaan Onarlioglu discovered that
    servers using Go Networking could hang during shutdown if preempted by a fatal error. An attacker could
    possibly use this to cause a denial of service. This issue only affected Ubuntu 22.04 LTS.
    (CVE-2022-27664)

    Arpad Ryszka and Jakob Ackermann discovered that a maliciously crafted stream could cause excessive CPU
    usage in Go Networking's HPACK decoder. An attacker could possibly use this to cause a denial of service.
    This issue only affected Ubuntu 22.04 LTS. (CVE-2022-41723)

    Mohammad Thoriq Aziz discovered that Go Networking did not properly sanitize some text nodes. An attacker
    could possibly use this to execute arbitrary code. This issue only affected Ubuntu 22.04 LTS.
    (CVE-2023-3978)

    Sean Ng discovered an error in Go Networking's HTML tag handling. An attacker could possibly use this to
    cause a denial of service. (CVE-2025-22872)

    Guido Vranken and Jakub Ciolek discovered that a maliciously crafted HTML document could exhaust system
    resources on servers using Go Networking. An attacker could possibly use this to cause a denial of
    service. (CVE-2025-47911)

    Guido Vranken discovered that a maliciously crafted HTML document could put servers using Go Networking
    into an infinite loop. An attacker could possibly use this to cause a denial of service. (CVE-2025-58190)
