"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2024:0165 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2023-45288:
    An attacker may cause an HTTP/2 endpoint to read arbitrary amounts of header data by sending an excessive
    number of CONTINUATION frames. Maintaining HPACK state requires parsing and processing all HEADERS and
    CONTINUATION frames on a connection. When a request's headers exceed MaxHeaderBytes, no memory is
    allocated to store the excess headers, but they are still parsed. This permits an attacker to cause an
    HTTP/2 endpoint to read arbitrary amounts of header data, all associated with a request which is going to
    be rejected. These headers can include Huffman-encoded data which is significantly more expensive for the
    receiver to decode than for an attacker to send. The fix sets a limit on the amount of excess header
    frames we will process before closing a connection.

    CVE-2023-45289:
    When following an HTTP redirect to a domain which is not a subdomain match or exact match of the initial
    domain, an http.Client does not forward sensitive headers such as Authorization or Cookie. For
    example, a redirect from foo.com to www.foo.com will forward the Authorization header, but a redirect to
    bar.com will not. A maliciously crafted HTTP redirect could cause sensitive headers to be unexpectedly
    forwarded.

    CVE-2023-45290:
    When parsing a multipart form (either explicitly with Request.ParseMultipartForm or implicitly with
    Request.FormValue, Request.PostFormValue, or Request.FormFile), limits on the total size of the parsed
    form were not applied to the memory consumed while reading a single form line. This permits a maliciously
    crafted input containing very long lines to cause allocation of arbitrarily large amounts of memory,
    potentially leading to memory exhaustion. With fix, the ParseMultipartForm function now correctly limits
    the maximum size of form lines.

    CVE-2024-24783:
    Verifying a certificate chain which contains a certificate with an unknown public key algorithm will cause
    Certificate.Verify to panic. This affects all crypto/tls clients, and servers that set Config.ClientAuth
    to VerifyClientCertIfGiven or RequireAndVerifyClientCert. The default behavior is for TLS servers to not
    verify client certificates.
