"The remote EulerOS host is missing multiple security updates.");
  script_set_attribute(attribute:"description", value:
"According to the versions of the golang packages installed, the EulerOS installation on the remote host is affected by
the following vulnerabilities :

  - In filepath.Clean in path/filepath in Go before 1.17.11 and 1.18.x before 1.18.3 on Windows, invalid paths
    such as .\c: could be converted to valid paths (such as c: in this example). (CVE-2022-29804)

  - 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 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 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)

  - Infinite loop in Read in crypto/rand before Go 1.17.11 and Go 1.18.3 on Windows allows attacker to cause
    an indefinite hang by passing a buffer larger than 1 << 32 - 1 bytes. (CVE-2022-30634)

  - Uncontrolled recursion in Decoder.Decode in encoding/gob before Go 1.17.12 and Go 1.18.4 allows an
    attacker to cause a panic due to stack exhaustion via a message which contains deeply nested structures.
    (CVE-2022-30635)

  - 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 too-short encoded message can cause a panic in Float.GobDecode and Rat GobDecode in math/big in Go
    before 1.17.13 and 1.18.5, potentially allowing a denial of service. (CVE-2022-32189)
