In versions 1.3.3 and prior, an unsigned integer underflow in the `Crypto_TC_ProcessSecurity` function of CryptoLib leads to a heap buffer overflow. The vulnerability is triggered when the `fl` (frame length) field in a Telecommand (TC) packet is set to 0. This underflow causes the frame length to be interpreted as 65535, resulting in out-of-bounds memory access. This critical vulnerability can be exploited to cause a denial of service (DoS) or potentially achieve remote code execution. Users of CryptoLib are advised to apply the recommended patch or avoid processing untrusted TC packets until a fix is available."}, {"lang": "es", "value": "CryptoLib ofrece una soluci\u00f3n exclusivamente de software que utiliza el Protocolo de Seguridad de Enlace de Datos Espaciales CCSDS - Procedimientos Extendidos (SDLS-EP) para proteger las comunicaciones entre una nave espacial que ejecuta el Sistema de Vuelo (cFS) y una estaci\u00f3n terrestre. En las versiones 1.3.3 y anteriores, un desbordamiento de entero sin signo en la funci\u00f3n `Crypto_TC_ProcessSecurity` de CryptoLib provoca un desbordamiento del b\u00fafer del mont\u00f3n. La vulnerabilidad se activa cuando el campo `fl` (longitud de trama) de un paquete de Telecomando (TC) se establece en 0. Este desbordamiento hace que la longitud de trama se interprete como 65535, lo que resulta en un acceso a memoria fuera de los l\u00edmites. Esta vulnerabilidad cr\u00edtica puede explotarse para provocar una denegaci\u00f3n de servicio (DoS) o, potencialmente, la ejecuci\u00f3n remota de c\u00f3digo. Se recomienda a los usuarios de CryptoLib que apliquen el parche recomendado o eviten procesar paquetes TC no confiables hasta que est\u00e9 disponible una soluci\u00f3n."}], "lastModified": "2025-05-07T20:42:18.853", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:nasa:cryptolib:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "9C930C9B-8C81-459A-AB6D-5F6D85290E1C", "versionEndExcluding": "1.4.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
