Vulnerability from variot

An Insufficient Entropy in PRNG vulnerability in Fortinet FortiOS 6.2.1, 6.2.0, 6.0.8 and below for device not enable hardware TRNG token and models not support builtin TRNG seed allows attacker to theoretically recover the long term ECDSA secret in a TLS client with a RSA handshake and mutual ECDSA authentication via the help of flush+reload side channel attacks in FortiGate VM models only. Fortinet FortiOS Contains a vulnerability related to lack of entropy.Information may be obtained. Fortinet FortiOS is a set of security operating system dedicated to the FortiGate network security platform developed by Fortinet. The system provides users with various security functions such as firewall, anti-virus, IPSec/SSLVPN, Web content filtering and anti-spam. Fortinet FortiOS versions 6.2.1, 6.2.0, 6.0.8 and earlier have security signature vulnerabilities in the deterministic (pseudo-random) number generator (PRNG). An attacker could exploit this vulnerability to obtain sensitive information
