Descriptions
RubyGems 2.0.x before 2.0.16, 2.2.x before 2.2.4, and 2.4.x before 2.4.7 does not validate the hostname when fetching gems or making API requests, which allows remote attackers to redirect requests to arbitrary domains via a crafted DNS SRV record, aka a "DNS hijack attack."
RubyGems 2.0.x en versiones anteriores a 2.0.16, 2.2.x en versiones anteriores a 2.2.4 y 2.4.x en versiones anteriores a 2.4.7 no valida el nombre de host al recuperar gemas o hacer solicitudes de API, lo que permite a atacantes remotos redireccionar peticiones a dominios arbitrarios a través del registro DNS SRV manipulado, también conocido como un "ataque de secuestro de DNS".
A flaw was found in a way rubygems verified the API endpoint hostname retrieved through a DNS SRV record. A man-in-the-middle attacker could use this flaw to force a client to download content from an untrusted domain.
