    Several vulnerabilities have been discovered in the interpreter for the
    Ruby language. The Common Vulnerabilities and Exposures project
    identifies the following problems:
    
    CVE-2018-16395
    
        Tyler Eckstein reported that the equality check of
        OpenSSL::X509::Name could return true for non-equal objects. If a
        malicious X.509 certificate is passed to compare with an existing
        certificate, there is a possibility to be judged incorrectly that
        they are equal.
    
    CVE-2018-16396
    
        Chris Seaton discovered that tainted flags are not propagated in
        Array#pack and String#unpack with some directives.
    
    For the stable distribution (stretch), these problems have been fixed in
    version 2.3.3-1+deb9u4.
    
    We recommend that you upgrade your ruby2.3 packages.
