Scientific Linux Security Update : postgresql and postgresql84 on SL5.x, SL6.x i386/x86_64 (20131029)

high Nessus Plugin ID 70705

Language:

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

An array index error, leading to a heap-based out-of-bounds buffer read flaw, was found in the way PostgreSQL performed certain error processing using enumeration types. An unprivileged database user could issue a specially crafted SQL query that, when processed by the server component of the PostgreSQL service, would lead to a denial of service (daemon crash) or disclosure of certain portions of server memory. (CVE-2013-0255)

A flaw was found in the way the pgcrypto contrib module of PostgreSQL (re)initialized its internal random number generator. This could lead to random numbers with less bits of entropy being used by certain pgcrypto functions, possibly allowing an attacker to conduct other attacks. (CVE-2013-1900)

These updated packages upgrade PostgreSQL to version 8.4.18, which fixes these issues as well as several non-security issues. Refer to the PostgreSQL Release Notes for a full list of changes :

http://www.postgresql.org/docs/8.4/static/release-8-4-18.html

After installing this update, it is advisable to rebuild, using the REINDEX command, Generalized Search Tree (GiST) indexes that meet one or more of the following conditions :

 - GiST indexes on box, polygon, circle, or point columns

 - GiST indexes for variable-width data types, that is text, bytea, bit, and numeric

 - GiST multi-column indexes

If the postgresql service is running, it will be automatically restarted after installing this update.

Solution

Update the affected packages.
