Synopsis
========
The PostgreSQL server can be tricked by a local attacker to execute
arbitrary code.
Background
==========
PostgreSQL is a SQL compliant, open source object-relational database
management system.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-db/postgresql < 7.4.7 >= 7.4.7
Description
===========
PostgreSQL's LOAD extension is vulnerable to a local privilege
escalation discovered by John Heasman. A local user can load any shared
library, but the initialization function will then be executed with the
permissions of the PostgreSQL server.
Impact
======
A malicious local user could exploit this to execute arbitrary code
with the privileges of the PostgreSQL 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-7.4.7"
