"The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 LTS / 22.04 LTS host has packages installed that are affected by
multiple vulnerabilities as referenced in the USN-6038-2 advisory.

    USN-6038-1 fixed several vulnerabilities in Go 1.18. This update provides the corresponding updates for Go
    1.13 and Go 1.16.

    CVE-2022-29526 and CVE-2022-30630 only affected Go 1.16.

    Original advisory details:

    It was discovered that the Go net/http module incorrectly handled

    Transfer-Encoding headers in the HTTP/1 client. A remote attacker could

    possibly use this issue to perform an HTTP Request Smuggling attack.

    (CVE-2022-1705)

    It was discovered that Go did not properly manage memory under certain

    circumstances. An attacker could possibly use this issue to cause a panic

    resulting into a denial of service. (CVE-2022-1962, CVE-2022-27664,

    CVE-2022-28131, CVE-2022-30630, CVE-2022-30631, CVE-2022-30632,

    CVE-2022-30633, CVE-2022-30635, CVE-2022-32189, CVE-2022-41715,

    CVE-2022-41717, CVE-2023-24534, CVE-2023-24537)

    It was discovered that Go did not properly implemented the maximum size of

    file headers in Reader.Read. An attacker could possibly use this issue to

    cause a panic resulting into a denial of service. (CVE-2022-2879)

    It was discovered that the Go net/http module incorrectly handled query

    parameters in requests forwarded by ReverseProxy. A remote attacker could

    possibly use this issue to perform an HTTP Query Parameter Smuggling attack.

    (CVE-2022-2880)

    It was discovered that Go did not properly manage the permissions for

    Faccessat function. A attacker could possibly use this issue to expose

    sensitive information. (CVE-2022-29526)

    It was discovered that Go did not properly generate the values for

    ticket_age_add in session tickets. An attacker could possibly use this

    issue to observe TLS handshakes to correlate successive connections by

    comparing ticket ages during session resumption. (CVE-2022-30629)

    It was discovered that Go did not properly manage client IP addresses in

    net/http. An attacker could possibly use this issue to cause ReverseProxy

    to set the client IP as the value of the X-Forwarded-For header.

    (CVE-2022-32148)

    It was discovered that Go did not properly validate backticks (`) as

    Javascript string delimiters, and do not escape them as expected. An

    attacker could possibly use this issue to inject arbitrary Javascript code

    into the Go template. (CVE-2023-24538)
