    Multiple vulnerabilities were found in Ruby on Rails, a MVC ruby-based
    framework geared for web application development, which could lead to
    remote code execution and untrusted user input usage, depending on the
    application.
    
    CVE-2020-8163
    
        A code injection vulnerability in Rails would allow an attacker
        who controlled the `locals` argument of a `render` call to perform
        a RCE.
    
    CVE-2020-8164
    
        A deserialization of untrusted data vulnerability exists in rails
        which can allow an attacker to supply information can be
        inadvertently leaked from Strong Parameters.
    
    CVE-2020-8165
    
       A deserialization of untrusted data vulnernerability exists in
       rails that can allow an attacker to unmarshal user-provided objects
       in MemCacheStore and RedisCacheStore potentially resulting in an
       RCE.
    
    For Debian 9 stretch, these problems have been fixed in version
    2:4.2.7.1-1+deb9u3.
    
    We recommend that you upgrade your rails packages.
