POWER9: In response to a denial of service vulnerability in OpenSSL, a new Power Systems firmware update is being released to address Common Vulnerabilities and Exposures issue number CVE-2018-0732.
A malicious server can send a large prime value to a client during DH(E) TLS handshake causing the client to hang. This can disrupt the HMC communications for system management and partition operations.
CVEID: CVE-2018-0732 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by the sending of a very large prime value to the client by a malicious server during key agreement in a TLS handshake. By spending an unreasonably long period of time generating a key for this prime, a remote attacker could exploit this vulnerability to cause the client to hang.
