Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2012-0866)

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.


2) SQL injection (CVE-ID: CVE-2012-0868)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

CRLF injection vulnerability in pg_dump 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 allows user-assisted remote attackers to execute arbitrary SQL commands via a crafted file containing object names with newlines, which are inserted into an SQL script that is used when the database is restored.
