Detail
| Problem Description: 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 use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/docs/DOC-11259 5. Bugs fixed (http://bugzilla.redhat.com/): 580187 - CVE-2010-0826 nss_db: Information leak due the DB_CONFIG file read from current working directory |
