The cryptographic key handling library, nkeys, recently gained support for encryption, not just for signing/authentication. This is used in nats-server 2.10 (Sep 2023) and newer for authentication callouts. In nkeys versions 0.4.0 through 0.4.5, corresponding with NATS server versions 2.10.0 through 2.10.3, the nkeys library's `xkeys` encryption handling logic mistakenly passed an array by value into an internal function, where the function mutated that buffer to populate the encryption key to use. As a result, all encryption was actually to an all-zeros key. This affects encryption only, not signing. \nFIXME: FILL IN IMPACT ON NATS-SERVER AUTH CALLOUT SECURITY. nkeys Go library 0.4.6, corresponding with NATS Server 2.10.4, has a patch for this issue. No known workarounds are available. For any application handling auth callouts in Go, if using the nkeys library, update the dependency, recompile and deploy that in lockstep."}, {"lang": "es", "value": "NATS.io es una tecnolog\u00eda de comunicaci\u00f3n distribuida pub-sub de c\u00f3digo abierto de alto rendimiento, creada para la nube, local, IoT y computaci\u00f3n de borde.

En las versiones 0.4.0 a 0.4.5 de nkeys, correspondientes a las versiones 2.10.0 a 2.10.3 del servidor NATS, la l\u00f3gica de manejo de cifrado `xkeys` de la librer\u00eda nkeys pas\u00f3 por error una matriz por valor a una funci\u00f3n interna, donde la funci\u00f3n mut\u00f3 ese b\u00fafer. para completar la clave de cifrado que se utilizar\u00e1.
