YAML deserialization of gem specifications can bypass class white lists. Specially crafted serialized objects can possibly be used to escalate to remote code execution.</p> <p><strong>Affected:</strong> HackerOne RubyGems</p> <p>RubyGems versions between 2.0.0 and 2.6.13 are vulnerable to a possible remote code execution vulnerability.

(CVE-2017-0901)</p> <p>It was discovered that Ruby was vulnerable to a DNS hijacking vulnerability. An attacker could use this to possibly force the RubyGems client to download and install gems from a server that the attacker controls.
