Synopsis:          Moderate: nss_db security update
Advisory ID:       RHSA-2010:0347-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://access.redhat.com/errata/RHSA-2010:0347.html

====================================================================
1. Summary:

Updated nss_db packages that fix one security issue are now available for
Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having moderate
security impact. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available from the CVE link in
the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64

3. Description:

The nss_db packages provide a set of C library extensions which allow
Berkeley Database (Berkeley DB) databases to be used as a primary source of
aliases, ethers, groups, hosts, networks, protocols, users, RPCs, services,
and shadow passwords. These databases are used instead of or in addition to
the flat files used by these tools by default.

It was discovered that nss_db did not specify a path to the directory to be
used as the database environment for the Berkeley Database library, causing
it to use the current working directory as the default. This could possibly
allow a local attacker to obtain sensitive information. (CVE-2010-0826)

Users of nss_db are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
