Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
EUVDB-ID: #VU53231
Risk: Medium
CVSSv3.1: 7.1 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-32027
CWE-ID:
CWE-190 - Integer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow when processing certain SQL array values during array subscribing calculation. An authenticated database user can pass specially crafted data to the application, trigger integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system and can be exploited by a remote unauthenticated attacker via SQL injection vulnerability in the frontend application.
Update the affected package postgresql12 to the latest version.

EUVDB-ID: #VU53232
Risk: Medium
CVSSv3.1: 6.7 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-32028
CWE-ID:
CWE-401 - Missing release of memory after effective lifetime
Exploit availability: No
DescriptionThe vulnerability allows a remote user to gain access to sensitive information.
The vulnerability exists due memory leak within the INSERT ... ON CONFLICT ... DO UPDATE
command implementation. A remote authenticated database user can execute the affected command to read arbitrary bytes of server memory. In the default
configuration, any authenticated database user can create prerequisite objects
and complete this attack at will.
Update the affected package postgresql12 to the latest version.

CVE-ID: CVE-2021-32029
CWE-ID:
CWE-401 - Missing release of memory after effective lifetime
Exploit availability: No
DescriptionThe vulnerability allows a remote user to gain access to sensitive information.
The vulnerability exists due memory leak when processing UPDATE ... RETURNING
command on a purpose-crafted partitioned table. A remote authenticated user can run the affected command and read arbitrary bytes of server memory. In the default
configuration, any authenticated database user can create prerequisite objects
and complete this attack at will.
Update the affected package postgresql12 to the latest version.
