"The remote Red Hat Enterprise Linux CoreOS 4 host has packages installed that are affected by multiple vulnerabilities
as referenced in the RHSA-2023:5009 advisory.

  - In net/http in Go before 1.18.6 and 1.19.x before 1.19.1, attackers can cause a denial of service because
    an HTTP/2 connection can hang during closing if shutdown were preempted by a fatal error. (CVE-2022-27664)

  - A use-after-free issue was discovered in Py_FindObjects() function in SciPy versions prior to 1.8.0. NOTE:
    the vendor and discoverer indicate that this is not a security issue. (CVE-2023-29824)

  - A compliance problem was found in the Red Hat OpenShift Container Platform. Red Hat discovered that, when
    FIPS mode was enabled, not all of the cryptographic modules in use were FIPS-validated. (CVE-2023-3089)

  - A flaw was found in Open Virtual Network where the service monitor MAC does not properly rate limit. This
    issue could allow an attacker to cause a denial of service, including on deployments with CoPP enabled and
    properly configured. (CVE-2023-3153)

  - goproxy v1.1 was discovered to contain an issue which can lead to a Denial of service (DoS) via
    unspecified vectors. (CVE-2023-37788)

  - The html/template package does not properly handle HTML-like  comment tokens, nor hashbang #! comment
    tokens, in <script> contexts. This may cause the template parser to improperly interpret the contents of
    <script> contexts, causing actions to be improperly escaped. This may be leveraged to perform an XSS
    attack. (CVE-2023-39318)

  - The html/template package does not apply the proper rules for handling occurrences of <script, <!--,
    and </script within JS literals in <script> contexts. This may cause the template parser to improperly
    consider script contexts to be terminated early, causing actions to be improperly escaped. This could be
    leveraged to perform an XSS attack. (CVE-2023-39319)

  - Processing an incomplete post-handshake message for a QUIC connection can cause a panic. (CVE-2023-39321)

  - QUIC connections do not set an upper bound on the amount of data buffered when reading post-handshake
    messages, allowing a malicious QUIC connection to cause unbounded memory growth. With fix, connections now
    consistently reject messages larger than 65KiB in size. (CVE-2023-39322)

  - A malicious HTTP/2 client which rapidly creates requests and immediately resets them can cause excessive
    server resource consumption. While the total number of requests is bounded by the
    http2.Server.MaxConcurrentStreams setting, resetting an in-progress request allows the attacker to create
    a new request while the existing one is still executing. With the fix applied, HTTP/2 servers now bound
    the number of simultaneously executing handler goroutines to the stream concurrency limit
    (MaxConcurrentStreams). New requests arriving when at the limit (which can only happen after the client
    has reset an existing, in-flight request) will be queued until a handler exits. If the request queue grows
    too large, the server will terminate the connection. This issue is also fixed in golang.org/x/net/http2
    for users manually configuring HTTP/2. The default stream concurrency limit is 250 streams (requests) per
    HTTP/2 connection. This value may be adjusted using the golang.org/x/net/http2 package; see the
    Server.MaxConcurrentStreams setting and the ConfigureServer function. (CVE-2023-39325)

  - Text nodes not in the HTML namespace are incorrectly literally rendered, causing text which should be
    escaped to not be. This could lead to an XSS attack. (CVE-2023-3978)

  - golang: net/http, x/net/http2: rapid stream resets can cause excessive work () (CVE-2023-44487)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
