"value": "The JS Compute Runtime for Fastly's Compute@Edge platform provides the environment JavaScript is executed in when using the Compute@Edge JavaScript SDK. In versions prior to 0.5.3, the `Math.random` and `crypto.getRandomValues` methods fail to use sufficiently random values. The initial value to seed the PRNG (pseudorandom number generator) is baked-in to the final WebAssembly module, making the sequence of random values for that specific WebAssembly module predictable. An attacker can use the fixed seed to predict random numbers generated by these functions and bypass cryptographic security controls, for example to disclose sensitive data encrypted by functions that use these generators. The problem has been patched in version 0.5.3. No known workarounds exist."

"value": "El JS Compute Runtime para la plataforma Compute@Edge de Fastly proporciona el entorno en el que se ejecuta JavaScript cuando se usa el SDK de JavaScript de Compute@Edge. En versiones anteriores a 0.5.3, los m\u00e9todos \"Math.random\" y \"crypto.getRandomValues\" no usan valores suficientemente aleatorios. El valor inicial para sembrar el PRNG (generador de n\u00fameros pseudoaleatorios) est\u00e1 incorporado en el m\u00f3dulo final de WebAssembly, haciendo que la secuencia de valores aleatorios para ese m\u00f3dulo espec\u00edfico de WebAssembly sea predecible. Un atacante puede usar la semilla fija para predecir los n\u00fameros aleatorios generados por estas funciones y omitir los controles de seguridad criptogr\u00e1ficos, por ejemplo para divulgar datos confidenciales cifrados por las funciones que usan estos generadores. El problema ha sido parcheado en versi\u00f3n 0.5.3. No se presentan mitigaciones conocidas"
