Descriptions

RubyGems is a package registry used to supply software for the Ruby language ecosystem. An ordering mistake in the code that accepts gem uploads allowed some gems (with platforms ending in numbers, like `arm64-darwin-21`) to be temporarily replaced in the CDN cache by a malicious package. The bug has been patched, and is believed to have never been exploited, based on an extensive review of logs and existing gems by rubygems. The easiest way to ensure that an application has not been exploited by this vulnerability is to verify all downloaded .gems checksums match the checksum recorded in the RubyGems.org database. RubyGems.org has been patched and is no longer vulnerable to this issue.

RubyGems es un registro de paquetes usado para suministrar software para el ecosistema del lenguaje Ruby. Un error de ordenación en el código que acepta la subida de gemas permitía que algunas gemas (con plataformas terminadas en números, como "arm64-darwin-21") fueran sustituidas temporalmente en la caché de la CDN por un paquete malicioso. El bug ha sido parcheado, y se cree que nunca ha sido explotado, basándose en una extensa revisión de registros y gemas existentes por parte de rubygems. La forma más fácil de asegurarse de que una aplicación no ha sido explotada por esta vulnerabilidad es verificar que todas las sumas de comprobación de los archivos .gems descargados coinciden con la suma de comprobación registrada en la base de datos de RubyGems.org. RubyGems.org ha sido parcheado y ya no es vulnerable a este problema
