openEuler 22.03 LTS update for postgresql
Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Missing Encryption of Sensitive Data
EUVDB-ID: #VU58113
Risk: Medium
CVSSv3.1: 5.9 [CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-23214
CWE-ID:
CWE-311 - Missing Encryption of Sensitive Data
Exploit availability: No
DescriptionThe 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.
Install updates from vendor's repository.

2) Missing Encryption of Sensitive Data
EUVDB-ID: #VU58114
Risk: Medium
CVSSv3.1: 5.9 [CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-23222
CWE-ID:
CWE-311 - Missing Encryption of Sensitive Data
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to the way the libpq process in PostgreSQL handles encrypted connections. A man-in-the-middle attacker can inject false responses to the client's first few queries, despite the use of SSL certificate verification and encryption. The attacker can exfiltrate the client's password or other confidential data that might be transmitted early in a session.
