Summary

IBM GCM16 & GCM32 and LCM8 & LCM16 KVM Switch Firmware have addressed the following vulnerabilities in OpenSSL.

Vulnerability Details

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.
CVSS Base Score: 3.7
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/144658&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L)

CVEID: CVE-2019-1559 DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by the failure to immediately close the TCP connection after the hosts encounter a zero-length record with valid padding. An attacker could exploit this vulnerability using a 0-byte record padding-oracle attack to decrypt traffic.
CVSS Base Score: 5.8
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/157514&gt; for the current score
CVSS Environmental Score*: Undefined
