Security Bulletin
Summary
This update addresses multiple CVEs that impacts any VM configured with a virtual trusted platform module (vTPM) version 1.2
Vulnerability Details
CVEID: CVE-2018-5407
DESCRIPTION: Multiple SMT/Hyper-Threading architectures and processors could allow a local attacker to obtain sensitive information, caused by executing 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 Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N)
CVEID: CVE-2009-3245
DESCRIPTION: An unspecified error in OpenSSL related to a missing check for a NULL return value from bn_wexpand function calls has an unknown impact and attack vector.
CVSS Base score: 4.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/56751 for the current score.
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)
CVEID: CVE-2014-0076
DESCRIPTION: OpenSSL could allow a local attacker to obtain sensitive information, caused by an implementation error in ECDSA (Elliptic Curve Digital Signature Algorithm). An attacker could exploit this vulnerability using the FLUSH+RELOAD cache side-channel attack to recover ECDSA nonces.
CVSS Base score: 2.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/91990 for the current score.
CVSS Vector: (AV:L/AC:L/Au:N/C:P/I:N/A:N)
CVEID: CVE-2022-0778
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a flaw in the BN_mod_sqrt() function when parsing certificates. By using a specially-crafted certificate with invalid explicit curve parameters, a remote attacker could exploit this vulnerability to cause an infinite loop, and results in a denial of service condition.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/221911 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

Disclaimer
According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
