GHSA-vqcq-mrmw-mcmg Rubyzip gem contains a Directory Traversal vulnerability in zip file component

• RubyGems rubyzip: < 1.2.2 → fixed in 1.2.2

rubyzip gem rubyzip 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.. This is similar to CVE-2017-5946 which was patched in 1.2.1 but the fix in that case was incomplete.
