Descriptions

The PRNG implementation for the OpenSSL FIPS Object Module 1.1.1 does not perform auto-seeding during the FIPS self-test, which generates random data that is more predictable than expected and makes it easier for attackers to bypass protection mechanisms that rely on the randomness.

La implementación PRNG para OpenSSL FIPS Object Module 1.1.1 no realiza una selección previa automática de la semilla durante el test de FIPS que realiza a sí mismo. Esto genera información arbitraria que es más predecible de lo esperado y hace que, para los atacantes, sea más fácil vulnerar los mecanismos de protección basados en aleatoriedad.

A significant flaw in the PRNG implementation for the OpenSSL FIPS Object Module v1.1.1 has been reported by Geoff Lowe of Secure Computing Corporation.
