"According to the versions of the golang packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :

  - The encoding/xml package in Go (all versions) does not
    correctly preserve the semantics of attribute namespace
    prefixes during tokenization round-trips, which allows
    an attacker to craft inputs that behave in conflicting
    ways during different stages of processing in affected
    downstream applications.(CVE-2020-29509)

  - The encoding/xml package in Go versions 1.15 and
    earlier does not correctly preserve the semantics of
    directives during tokenization round-trips, which
    allows an attacker to craft inputs that behave in
    conflicting ways during different stages of processing
    in affected downstream applications.(CVE-2020-29510)

  - The encoding/xml package in Go (all versions) does not
    correctly preserve the semantics of element namespace
    prefixes during tokenization round-trips, which allows
    an attacker to craft inputs that behave in conflicting
    ways during different stages of processing in affected
    downstream applications.(CVE-2020-29511)

  - Go before 1.14.12 and 1.15.x before 1.15.5 allows
    Argument Injection.(CVE-2020-28367)

  - Go before 1.14.12 and 1.15.x before 1.15.5 allows Code
    Injection.(CVE-2020-28366)
