Descriptions

A flaw was found in GnuTLS. The Minerva attack is a cryptographic vulnerability that exploits deterministic behavior in systems like GnuTLS, leading to side-channel leaks. In specific scenarios, such as when using the GNUTLS_PRIVKEY_FLAG_REPRODUCIBLE flag, it can result in a noticeable step in nonce size from 513 to 512 bits, exposing a potential timing side-channel.

Se encontró una falla en GnuTLS. El ataque Minerva es una vulnerabilidad criptográfica que explota el comportamiento determinista en sistemas como GnuTLS, lo que genera filtraciones de canales laterales. En escenarios específicos, como cuando se usa el indicador GNUTLS_PRIVKEY_FLAG_REPRODUCIBLE, puede resultar en un paso notable en el tamaño del nonce de 513 a 512 bits, exponiendo un posible canal lateral de temporización.
