Summary

IBM DataPower Gateway has addressed the following vulnerabilities:
CVE-2018-0734 CVE-2018-5407

Vulnerability Details

CVEID: CVE-2018-0734
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive
information, caused by a timing side channel attack in the DSA signature
algorithm. An attacker could exploit this vulnerability using variations in the
signing algorithm to recover the private key.
CVSS Base Score: 3.7
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
152085 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N)

CVEID: CVE-2018-5407
DESCRIPTION: Multiple SMT/Hyper-Threading architectures and processors could
allow a local attacker to obtain sensitive information, caused by execution
engine sharing on Simultaneous Multithreading (SMT) architecture. By using the
PortSmash new side-channel attack, an attacker could run a malicious process
next to legitimate processes using the architectures parallel thread running
capabilities to leak encrypted data from the CPU's internal processes. Note:
This vulnerability is known as PortSmash.
CVSS Base Score: 5.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
152484 for the current score
