SB2022030451 - Anolis OS update for postgresql:12 module

Description

This security bulletin contains information about 2 vulnerabilities.

1) Missing Encryption of Sensitive Data (CVE-ID: CVE-2021-23214)

CWE-ID: CWE-311 - Missing Encryption of Sensitive Data

CVSSv4: CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to the way PostgreSQL handles encrypted connections. When the server is configured to use trust authentication with a clientcert requirement or to use cert authentication, a man-in-the-middle attacker can inject arbitrary SQL queries when a connection is first established, despite the use of SSL certificate verification and encryption.

2) Memory leak (CVE-ID: CVE-2021-3677)

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a remote user to perform DoS attack or gain access to sensitive information.

The vulnerability exists due memory leak during parallel sort operations. A remote user can force the application to leak memory and perform denial of service attack or read arbitrary memory parts on the system.

Remediation

Install update from vendor's website.
