high Nessus Plugin ID 140313

Language:

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

Manuel Pegourie-Gonnard reports :

An attacker with access to precise enough timing and memory access information (typically an untrusted operating system attacking a secure enclave such as SGX or the TrustZone secure world) can recover the private keys used in RSA or static (finite-field) Diffie-Hellman operations.

Solution

Update the affected package.
