Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Improper privilege management

EUVDB-ID: #VU100511

Risk: Medium

CVSSv4.0: 1.3 [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]

CVE-ID: CVE-2024-10976

CWE-ID: CWE-269 - Improper Privilege Management

Exploit availability: No

Description

The vulnerability allows a remote user to bypass implemented security restrictions.

The vulnerability exists due to improper privilege management in cases where a subquery, WITH query, security invoker view, or SQL-language function references a table with a row-level security policy. A remote user can bypass implemented security restrictions and gain unauthorized access to the database in cases where role-specific policies are used and a given query is planned under one role and then executed under other roles.

Mitigation

Update the affected package postgresql-9.5 to the latest version.

Vulnerable software versions

Ubuntu: 16.04

postgresql-client-9.5 (Ubuntu package): before Ubuntu Pro

postgresql-9.5 (Ubuntu package): before Ubuntu Pro (Infra-only)
