Multiple vulnerabilities in PostgreSQL

1) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU43839

Risk: Low

CVSSv3.1: 3 [CVSS:3.1/AV:N/AC:L/PR:/UI:N/S:U/C:L/I:L/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2012-0866

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

The vulnerability allows a remote #AU# to read and manipulate data.

CREATE TRIGGER in PostgreSQL 8.3.x before 8.3.18, 8.4.x before 8.4.11, 9.0.x before 9.0.7, and 9.1.x before 9.1.3 does not properly check the execute permission for trigger functions marked SECURITY DEFINER, which allows remote authenticated users to execute otherwise restricted triggers on arbitrary data by installing the trigger on an attacker-owned table.

Mitigation

Install update from vendor's website.
