Severity:	normal
Title:	PostgreSQL: Multiple vulnerabilities
Date:	02/07/2005
Bugs:	#80342
ID:	200502-08

Synopsis

PostgreSQL contains several vulnerabilities which could lead to execution of arbitrary code, Denial of Service and security bypass.

Background

PostgreSQL is a SQL compliant, open source object-relational database management system.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
dev-db/postgresql	< 7.3.10	== 7.3*	All supported architectures

Description

PostgreSQL's contains several vulnerabilities:

John Heasman discovered that the LOAD extension is vulnerable to local privilege escalation (CAN-2005-0227).
It is possible to bypass the EXECUTE permission check for functions (CAN-2005-0244).
The PL/PgSQL parser is vulnerable to heap-based buffer overflow (CAN-2005-0244).
The intagg contrib module is vulnerable to a Denial of Service (CAN-2005-0246).

Impact

An attacker could exploit this to execute arbitrary code with the privileges of the PostgreSQL server, bypass security restrictions and crash the server.

Workaround

There is no know workaround at this time.

Resolution

All PostgreSQL users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose dev-db/postgresql
