* rubygems: Path traversal when writing to a symlinked basedir outside of
the root (CVE-2018-1000073)

* rubygems: Unsafe Object Deserialization Vulnerability in gem owner
allowing arbitrary code execution on specially crafted YAML
(CVE-2018-1000074)

* rubygems: Improper verification of signatures in tarball allows to
install mis-signed gem (CVE-2018-1000076)

* rubygems: Missing URL validation on spec home attribute allows malicious
gem to set an invalid homepage URL (CVE-2018-1000077)

* rubygems: XSS vulnerability in homepage attribute when displayed via gem
server (CVE-2018-1000078)

* rubygems: Path traversal issue during gem installation allows to write to
