Descriptions

RubyGems.org is the Ruby community gem host. A bug in password & email change confirmation code allowed an attacker to change their RubyGems.org account's email to an unowned email address. Having access to an account whose email has been changed could enable an attacker to save API keys for that account, and when a legitimate user attempts to create an account with their email (and has to reset password to gain access) and is granted access to other gems, the attacker would then be able to publish and yank versions of those gems. Commit number 90c9e6aac2d91518b479c51d48275c57de492d4d contains a patch for this issue.

RubyGems.org es el host de gemas de la comunidad Ruby. Un error en el código de confirmación de cambio de contraseña y correo electrónico permitía a un atacante cambiar el correo electrónico de su cuenta de RubyGems.org a una dirección de correo electrónico no propia. Tener acceso a una cuenta cuyo correo electrónico ha sido cambiado podría permitir a un atacante guardar las claves de la API para esa cuenta, y cuando un usuario legítimo intente crear una cuenta con su correo electrónico (y tenga que restablecer la contraseña para acceder) y le sea concedido acceso a otras gemas, el atacante podría entonces publicar y arrancar versiones de esas gemas. El commit número 90c9e6aac2d91518b479c51d48275c57de492d4d contiene un parche para este problema
