(RHSA-2010:0347) Moderate: nss_db security update

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.
