    rubyzip gem version 1.2.1 and earlier contains a Directory Traversal
    vulnerability in Zip::File component that can result in write
    arbitrary files to the filesystem.
    
    This attack appear to be exploitable via if a site allows
    uploading of .zip files, an attacker can upload a malicious file
    that contains symlinks or files with absolute pathnames "../"
    to write arbitrary files to the filesystem..
    
    For Debian 9 stretch, this problem has been fixed in version
    1.2.0-1.1+deb9u1.
    
    We recommend that you upgrade your ruby-zip packages.
