Summary
OpenSSL vulnerabilities affect IBM i. IBM i has addressed the applicable CVEs.
Vulnerability Details
CVEID: CVE-2016-0701
DESCRIPTION: OpenSSL could allow a remote attacker to conduct man-in-the-middle attacks, caused by the use of weak Diffie-Hellman parameters based on unsafe primes that are generated and stored in X9.42-style parameter files. By performing multiple handshakes using the same private DH exponent, an attacker could exploit this vulnerability to conduct man-in-the-middle attacks.
CVSS Base Score: 5.4
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/110234 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N)
