"The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the
ELSA-2022-7529 advisory.

  - Acceptance of some invalid Transfer-Encoding headers in the HTTP/1 client in net/http before Go 1.17.12
    and Go 1.18.4 allows HTTP request smuggling if combined with an intermediate server that also improperly
    fails to reject the header as invalid. (CVE-2022-1705)

  - In Decoder.Skip in encoding/xml in Go before 1.17.12 and 1.18.x before 1.18.4, stack exhaustion and a
    panic can occur via a deeply nested XML document. (CVE-2022-28131)

  - Uncontrolled recursion in Reader.Read in compress/gzip before Go 1.17.12 and Go 1.18.4 allows an attacker
    to cause a panic due to stack exhaustion via an archive containing a large number of concatenated 0-length
    compressed files. (CVE-2022-30631)

  - Uncontrolled recursion in Unmarshal in encoding/xml before Go 1.17.12 and Go 1.18.4 allows an attacker to
    cause a panic due to stack exhaustion via unmarshalling an XML document into a Go struct which has a
    nested field that uses the 'any' field tag. (CVE-2022-30633)

  - Improper exposure of client IP addresses in net/http before Go 1.17.12 and Go 1.18.4 can be triggered by
    calling httputil.ReverseProxy.ServeHTTP with a Request.Header map containing a nil value for the
    X-Forwarded-For header, which causes ReverseProxy to set the client IP as the value of the X-Forwarded-For
    header. (CVE-2022-32148)

  - A vulnerability was found in CRI-O that causes memory or disk space exhaustion on the node for anyone with
    access to the Kube API. The ExecSync request runs commands in a container and logs the output of the
    command. This output is then read by CRI-O after command execution, and it is read in a manner where the
    entire file corresponding to the output of the command is read in. Thus, if the output of the command is
    large it is possible to exhaust the memory or the disk space of the node when CRI-O reads the output of
    the command. The highest threat from this vulnerability is system availability. (CVE-2022-1708)

  - client_golang is the instrumentation library for Go applications in Prometheus, and the promhttp package
    in client_golang provides tooling around HTTP servers and clients. In client_golang prior to version
    1.11.1, HTTP server is susceptible to a Denial of Service through unbounded cardinality, and potential
    memory exhaustion, when handling requests with non-standard HTTP methods. In order to be affected, an
    instrumented software must use any of `promhttp.InstrumentHandler*` middleware except `RequestsInFlight`;
    not filter any specific methods (e.g GET) before middleware; pass metric with `method` label name to our
    middleware; and not have any firewall/LB/proxy that filters away requests with unknown `method`.
    client_golang version 1.11.1 contains a patch for this issue. Several workarounds are available, including
    removing the `method` label name from counter/gauge used in the InstrumentHandler; turning off affected
    promhttp handlers; adding custom middleware before promhttp handler that will sanitize the request method
    given by Go http.Request; and using a reverse proxy or web application firewall, configured to only allow
    a limited set of methods. (CVE-2022-21698)

  - Uncontrolled recursion in Glob in path/filepath before Go 1.17.12 and Go 1.18.4 allows an attacker to
    cause a panic due to stack exhaustion via a path containing a large number of path separators.
    (CVE-2022-30632)

  - Uncontrolled recursion in the Parse functions in go/parser before Go 1.17.12 and Go 1.18.4 allow an
    attacker to cause a panic due to stack exhaustion via deeply nested types or declarations. (CVE-2022-1962)

  - Uncontrolled recursion in Glob in io/fs before Go 1.17.12 and Go 1.18.4 allows an attacker to cause a
    panic due to stack exhaustion via a path which contains a large number of path separators.
    (CVE-2022-30630)
