    It was discovered that the Go net/http module did not properly handle the requests when request\'s headers
    exceed MaxHeaderBytes. An attacker could possibly use this issue to cause a panic resulting into a denial
    of service. This issue only affected Go 1.21 in Ubuntu 20.04 LTS and Ubuntu 22.04 LTS. (CVE-2023-45288)

    It was discovered that the Go net/http module did not properly validate the subdomain match or exact match
    of the initial domain. An attacker could possibly use this issue to read sensitive information. This issue
    only affected Go 1.21 in Ubuntu 20.04 LTS and Ubuntu 22.04 LTS. (CVE-2023-45289)

    It was discovered that the Go net/http module did not properly validate the total size of the parsed form
    when parsing a multipart form. An attacker could possibly use this issue to cause a panic resulting into a
    denial of service. This issue only affected Go 1.21 in Ubuntu 20.04 LTS and Ubuntu 22.04 LTS.
    (CVE-2023-45290)

    It was discovered that the Go crypto/x509 module did not properly handle a certificate chain which
    contains a certificate with an unknown public key algorithm. An attacker could possibly use this issue to
    cause a panic resulting into a denial of service. This issue only affected Go 1.21 in Ubuntu 20.04 LTS and
    Ubuntu 22.04 LTS. (CVE-2024-24783)

    It was discovered that the Go net/mail module did not properly handle comments within display names in the
    ParseAddressList function. An attacker could possibly use this issue to cause a panic resulting into a
    denial of service. This issue only affected Go 1.21 in Ubuntu 20.04 LTS and Ubuntu 22.04 LTS.
    (CVE-2024-24784)

    It was discovered that the Go html/template module did not validate errors returned from MarshalJSON
    methods. An attacker could possibly use this issue to inject arbitrary code into the Go template. This
    issue only affected Go 1.21 in Ubuntu 20.04 LTS and Ubuntu 22.04 LTS. (CVE-2024-24785)

    It was discovered that the Go net module did not properly validate the DNS message in response to a query.
    An attacker could possibly use this issue to cause a panic resulting into a denial of service. This issue
    only affected Go 1.22. (CVE-2024-24788)

    It was discovered that the Go archive/zip module did not properly handle certain types of invalid zip
    files differs from the behavior of most zip implementations. An attacker could possibly use this issue to
    cause a panic resulting into a denial of service. (CVE-2024-24789)

    It was discovered that the Go net/netip module did not work as expected for IPv4-mapped IPv6 addresses in
    various Is methods. An attacker could possibly use this issue to cause a panic resulting into a denial of
    service. (CVE-2024-24790)
