"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.

For the detailed security status of ruby-zip please refer to its
security tracker page at:
