Debian DLA-432-1 : postgresql-8.4 update

high Nessus Plugin ID 88973

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Several bugs were discovered in PostgreSQL, a relational database server system. The 8.4 branch is EOLed upstream, but still present in Debian squeeze. This new LTS minor version contains fixes that were applied upstream to the 9.1.20 version, backported to 8.4.22 which was the last version officially released by the PostgreSQL developers.
This LTS effort for squeeze-lts is a community project sponsored by credativ GmbH.

This release is the last LTS update for PostgreSQL 8.4. Users should migrate to a newer PostgreSQL at the earliest opportunity.

## Migration to Version 8.4.22lts6

A dump/restore is not required for those running 8.4.X. However, if you are upgrading from a version earlier than 8.4.22, see the relevant release notes.

## Fixes

Fix infinite loops and buffer-overrun problems in regular expressions (Tom Lane)

Very large character ranges in bracket expressions could cause infinite loops in some cases, and memory overwrites in other cases.
(CVE-2016-0773)

Perform an immediate shutdown if the postmaster.pid file is removed (Tom Lane)

The postmaster now checks every minute or so that postmaster.pid is still there and still contains its own PID. If not, it performs an immediate shutdown, as though it had received SIGQUIT. The main motivation for this change is to ensure that failed buildfarm runs will get cleaned up without manual intervention; but it also serves to limit the bad effects if a DBA forcibly removes postmaster.pid and then starts a new postmaster.

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.
