Vulnerability from fkie_nvd - Published: 2025-06-03 23:15 - Updated: 2025-06-09 15:11
Severity ?
5.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N
Summary
Deno is a JavaScript, TypeScript, and WebAssembly runtime. Versions 1.46.0 through 2.1.6 have an issue that affects AES-256-GCM and AES-128-GCM in Deno in which the authentication tag is not being validated. This means tampered ciphertexts or incorrect keys might not be detected, which breaks the guarantees expected from AES-GCM. Older versions of Deno correctly threw errors in such cases, as does Node.js. Without authentication tag verification, AES-GCM degrades to essentially CTR mode, removing integrity protection. Authenticated data set with set_aad is also affected, as it is incorporated into the GCM hash (ghash) but this too is not validated, rendering AAD checks ineffective. Version 2.1.7 includes a patch that addresses this issue.

      "value": "Deno es un entorno de ejecuci\u00f3n de JavaScript, TypeScript y WebAssembly con valores predeterminados seguros. Las versiones 1.46.0 a 2.1.6 presentan un problema que afecta a AES-256-GCM y AES-128-GCM en Deno, donde la etiqueta de autenticaci\u00f3n no se valida. Esto implica que podr\u00edan no detectarse textos cifrados alterados o claves incorrectas, lo que incumple las garant\u00edas esperadas de AES-GCM. Las versiones anteriores de Deno, al igual que Node.js, generaban errores correctamente en estos casos. Sin la verificaci\u00f3n de la etiqueta de autenticaci\u00f3n, AES-GCM se degrada al modo CTR, eliminando la protecci\u00f3n de integridad. El conjunto de datos autenticado con set_aad tambi\u00e9n se ve afectado, ya que se incorpora al hash de GCM (ghash), pero este tampoco se valida, lo que inutiliza las comprobaciones de AAD. La versi\u00f3n 2.1.7 incluye un parche que soluciona este problema."
