Description Andrej Nemec 2017-03-01 14:48:01 UTC 
The Zip::File component in the rubyzip gem for Ruby has a directory traversal vulnerability. If a site allows uploading of .zip files, an attacker can upload a malicious file that uses "../" pathname substrings to write arbitrary files to the filesystem.
