The vulnerability of the PRNG component of the FortiOS operating system allows a hacker to gain unauthorized access to protected information.

The vulnerability of the PRNG component in the FortiOS operating system relates to the use of a weak entropy source during key generation. Exploiting this vulnerability could allow an attacker, operating remotely, to gain unauthorized access to protected information, when FortiOS acts as a client...

Security Bulletin: Aspera Web Applications (Faspex, Console, Orchestrator) are affected by OpenSSL Vulnerabilities (CVE-2019-1547, CVE-2019-1549, CVE-2019-1563)

Summary Aspera Web Applications Faspex, Console, Orchestrator have addressed the following OpenSSL Vulnerabilities. Vulnerability Details CVEID: CVE-2019-1547 DESCRIPTION: Normally in OpenSSL EC groups always have a co-factor present and this is used in side channel resistant code paths. However,...

FreeBSD : Mbed TLS -- Side channel attack on ECDSA (b70b880f-5727-11ea-a2f3-001cc0382b2f)

Janos Follath reports : Our bignum implementation is not constant time/constant trace, so side channel attacks can retrieve the blinded value, factor it as it is smaller than RSA keys and not guaranteed to have only large prime factors, and then, by brute force, recover the key. C Tenable Network...
