Summary

OpenSSL vulnerabilities were disclosed on October 30 2018 and November 2 2018 by the OpenSSL Project. OpenSSL is used by IBM Rational ClearQuest. IBM Rational ClearQuest has addressed the applicable CVE.

Vulnerability Details

CVEID: CVE-2018-0734 DESCRIPTION: The OpenSSL DSA signature algorithm has been shown to be vulnerable to a timing side channel attack. An attacker could use 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 architecture’s 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
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N)
