RubyGems is vulnerable to privilege escalation attacks. A remote, unauthenticated attacker could elevate their privileges by interacting with the terminal via the use of escape sequences with a specifically crafted gem. Improper sanitization of gems’ specification text enables the attacker to exploit this vulnerability.
