The vulnerability allows a remote user to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application in the aggregate function calls when handling "unknown"-type arguments. A remote user can read parts of system memory.
2) Integer overflow (CVE-ID: CVE-2023-5869)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote user to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in array modification. A remote user can pass specially crafted data to the application, trigger an integer overflow and execute arbitrary code on the target system.
3) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-5870)
CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote user to perform a denial of service (DoS) attack.

CWE-ID: CWE-269 - Improper Privilege Management
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote user to escalate privileges within the database.
The vulnerability exists due to late privilege drop in REFRESH MATERIALIZED VIEW CONCURRENTLY. A remote user who is an object creator can execute arbitrary SQL functions as the command issuer.
5) Missing Authorization (CVE-ID: CVE-2024-4317)
CWE-ID: CWE-862 - Missing Authorization
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote user to gain access to sensitive information.
The vulnerability exists due to missing authorization in PostgreSQL built-in views pg_stats_ext and pg_stats_ext_exprs. A remote user can read most common values and other statistics from CREATE STATISTICS commands of other users.
