Security Bulletin: Vulnerabilities in PostgreSQL, Golang might affect IBM Spectrum Copy Data Management

Summary

IBM Spectrum Copy Data Management can be affected by vulnerabilities in PostgreSQL, and Golang Go. Vulnerabilities include causing a denial of service condition, sending a specially crafted request to launch further attacks against the affected system, and executing arbitrary code on the system, as described by the CVEs in the “Vulnerability Details” section.

Vulnerability Details

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-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.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:N/A:L)

CVEID:CVE-2023-45285
**DESCRIPTION:**Golang Go could allow a remote attacker to obtain sensitive information, caused by a flaw when using go get to fetch a module with the “.git” suffix. By sending a specially crafted request, an attacker could exploit this vulnerability to obtain sensitive information from the insecure “git://” protocol, and use this information to launch further attacks against the affected system.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/273323 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N)

CVEID:CVE-2023-39326
**DESCRIPTION:**Golang Go could allow a remote attacker to obtain sensitive information, caused by a flaw in the net/http package. By sending a specially crafted HTTP request, an attacker could exploit this vulnerability to read many more bytes from the network than are in the body, and use this information to launch further attacks against the affected system.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/273322 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)

CVEID:CVE-2023-45283
**DESCRIPTION:**Golang Go could allow a remote attacker to traverse directories on the system, caused by the failure to recognize paths with a ??\ prefix as a Root Local Device path prefix in the filepath and safefilepath package. An attacker could send a specially crafted URL request containing “dot dot” sequences (/…/) to view arbitrary files on the system.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/270990 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)

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.
