Synopsis: Moderate: postgresql and postgresql84 security update
Advisory ID: SLSA-2013:1475-1
Issue Date: 2013-10-29
CVE Numbers: CVE-2013-0255
 CVE-2013-1900
--

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:

https://www.postgresql.org/docs/8.4/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.
