IBM Storage Scale System has addressed the applicable CVEs. CVE-2023-5868, CVE-2020-21469, CVE-2023-5869, CVE-2024-0985, CVE-2023-5870.
Vulnerability Details
CVEID: CVE-2023-5868
DESCRIPTION: PostgreSQL could allow a remote authenticated attacker to obtain sensitive information, caused by a flaw when perform certain aggregate function calls. By sending a specially crafted request, an attacker could exploit this vulnerability to obtain bytes of server memory from the end of the "unknown"-type value to the next zero byte, and use this information to launch further attacks against the affected system.
CVSS Base score: 4.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/271219 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N)
CVEID: CVE-2020-21469
DESCRIPTION: PostgreSQL is vulnerable to a denial of service, caused by a buffer overflow. By sending specially crafted SIGHUP signals, a remote attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/266327 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)
CVEID: CVE-2023-5869
DESCRIPTION: PostgreSQL is vulnerable to a buffer overflow, caused by improper bounds checking by the SQL array values. By sending a specially crafted request, a remote authenticated attacker could overflow a buffer and execute arbitrary code on the system.
CVSS Base score: 8.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/271226 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)
CVEID: CVE-2024-0985
DESCRIPTION: PostgreSQL could allow a remote authenticated attacker to bypass security restrictions, caused by a flaw when running in REFRESH MATERIALIZED VIEW CONCURRENTLY. By persuading a victim to run command a specially crafted view, an attacker could exploit this vulnerability to execute arbitrary SQL functions as the command issuer.
CVSS Base score: 8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/282771 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H)
CVEID: CVE-2023-5870
DESCRIPTION: PostgreSQL is vulnerable to a denial of service, caused by a flaw in the pg_signal_backend role. By sending a specially crafted request, a remote authenticated attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 2.2
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/271227 for the current score.

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.
