"The remote Ubuntu 20.04 LTS / 22.04 LTS / 24.04 LTS host has packages installed that are affected by multiple
vulnerabilities as referenced in the USN-7081-1 advisory.

    It was discovered that the Go net/http module did not properly handle

    responses to requests with an Expect: 100-continue header under certain circumstances. An attacker could
    possibly use this issue to cause a denial of service. (CVE-2024-24791)

    It was discovered that the Go parser module did not properly handle deeply nested literal values. An
    attacker could possibly use this issue to cause a panic resulting in a denial of service. (CVE-2024-34155)

    It was discovered that the Go encoding/gob module did not properly handle message decoding under certain
    circumstances. An attacker could possibly use this issue to cause a panic resulting in a denial of
    service. (CVE-2024-34156)

    It was discovered that the Go build module did not properly handle certain build tag lines with deeply
    nested expressions. An attacker could possibly use this issue to cause a panic resulting in a denial of
    service. (CVE-2024-34158)

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