Security Bulletin
Summary
IBM DataPower Gateway has addressed the following vulnerabilities:
CVE-2018-0734
CVE-2018-5407
Vulnerability Details
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)
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
