    Multiple vulnerabilities have been discovered in jruby, Java
    implementation of the Ruby programming language.
    
    CVE-2018-1000074
    
        Deserialization of Untrusted Data vulnerability in owner command
        that can result in code execution. This attack appear to be
        exploitable via victim must run the `gem owner` command on a gem
        with a specially crafted YAML file
    
    CVE-2018-1000075
    
        an infinite loop caused by negative size vulnerability in ruby gem
        package tar header that can result in a negative size could cause an
        infinite loop
    
    CVE-2018-1000076
    
        Improper Verification of Cryptographic Signature vulnerability in
        package.rb that can result in a mis-signed gem could be installed,
        as the tarball would contain multiple gem signatures.
    
    CVE-2018-1000077
    
        Improper Input Validation vulnerability in ruby gems specification
        homepage attribute that can result in a malicious gem could set an
        invalid homepage URL
    
    CVE-2018-1000078
    
        Cross Site Scripting (XSS) vulnerability in gem server display of
        homepage attribute that can result in XSS. This attack appear to be
        exploitable via the victim must browse to a malicious gem on a
        vulnerable gem server
    
    CVE-2019-8321
    
        Gem::UserInteraction#verbose calls say without escaping, escape
        sequence injection is possible
    
    CVE-2019-8322
    
        The gem owner command outputs the contents of the API response
        directly to stdout. Therefore, if the response is crafted, escape
        sequence injection may occur
    
    CVE-2019-8323
    
        Gem::GemcutterUtilities#with_response may output the API response to
        stdout as it is. Therefore, if the API side modifies the response,
        escape sequence injection may occur.
    
    CVE-2019-8324
    
        A crafted gem with a multi-line name is not handled correctly.
        Therefore, an attacker could inject arbitrary code to the stub line
        of gemspec
    
    CVE-2019-8325
    
        Gem::CommandManager#run calls alert_error without escaping, escape
        sequence injection is possible. (There are many ways to cause an
        error.)
    
    For Debian 8 "Jessie", these problems have been fixed in version
    1.5.6-9+deb8u1.
    
    We recommend that you upgrade your jruby packages.
