Debian DLA-19-1 : postgresql-8.4 update

medium Nessus Plugin ID 82167

Language:

Synopsis

The remote Debian host is missing a security update.

Description

New upstream minor release. Users should upgrade to this version at their next scheduled maintenance window.

Noteworthy change :

Secure Unix-domain sockets of temporary postmasters started during make check (Noah Misch)

Any local user able to access the socket file could connect as the server's bootstrap superuser, then proceed to execute arbitrary code as the operating-system user running the test, as we previously noted in CVE-2014-0067. This change defends against that risk by placing the server's socket in a temporary, mode 0700 subdirectory of /tmp.

8.4.22 marks the end of life of the PostgreSQL 8.4 branch. No further releases will be made by the PostgreSQL Global Development Group.

Users of PostgreSQL 8.4 should look into upgrading to a newer PostgreSQL release. Options are :

- Upgrading to Debian 7 (Wheezy), providing postgresql-9.1.

- The use of the apt.postgresql.org repository, providing packages for all active PostgreSQL branches (9.0 up to 9.4 at the time of writing).

See https://wiki.postgresql.org/wiki/Apt for more information about the repository.

A helper script to activate the repository is provided in /usr/share/doc/postgresql-8.4/examples/apt.postgresql.or g.sh.

- An LTS version of 8.4 is in planning that will cover the lifetime of squeeze-lts. Updates will probably made on a best-effort basis. Users can take advantage of this, but should still consider upgrading to newer PostgreSQL versions over the next months.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
