    Multiple vulnerabilities were discovered in the interpreter for the Ruby
    language:
    
    CVE-2015-9096
    
        SMTP command injection in Net::SMTP.
    
    CVE-2016-7798
    
        Incorrect handling of initialization vector in the GCM mode in the
        OpenSSL extension.
    
    CVE-2017-0900
    
        Denial of service in the RubyGems client.
    
    CVE-2017-0901
    
        Potential file overwrite in the RubyGems client.
    
    CVE-2017-0902
    
        DNS hijacking in the RubyGems client.
    
    CVE-2017-14064
    
        Heap memory disclosure in the JSON library.
    
    For the stable distribution (stretch), these problems have been fixed in
    version 2.3.3-1+deb9u1. This update also hardens RubyGems against
    malicious termonal escape sequences (CVE-2017-0899).
    
    We recommend that you upgrade your ruby2.3 packages.
