"From Red Hat Security Advisory 2010:0347 :

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.

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."
