CentOS Update for bind97 CESA-2014:1244 centos5

CVSS Base Vector:

Technical Details:
The Berkeley Internet Name Domain (BIND) is an implementation of the Domain Name System (DNS) protocols. It contains a DNS server (named), a resolver library with routines for applications to use when interfacing with DNS, and tools for verifying that the DNS server is operating correctly. These Linux Distribution Packages contain version 9.7 of the BIND suite. A denial of service flaw was found in the way BIND handled queries for NSEC3-signed zones. A remote attacker could use this flaw against an authoritative name server that served NCES3-signed zones by sending a specially crafted query, which, when processed, would cause named to crash. (CVE-2014-0591) Note: The CVE-2014-0591 issue does not directly affect the version of bind97 shipped in Red Hat Enterprise Linux 5. This issue is being addressed however to assure it is not introduced in future builds of bind97 (possibly built with a different compiler or C library optimization). This update also fixes the following bug: * Previously, the bind97 initscript did not check for the existence of the ROOTDIR variable when shutting down the named daemon. As a consequence, some parts of the file system that are mounted when using bind97 in a chroot environment were unmounted on daemon shut down, even if bind97 was not running in a chroot environment. With this update, the initscript has been fixed to check for the existence of the ROOTDIR variable when unmounting some parts of the file system on named daemon shut down. Now, when shutting down bind97 that is not running in a chroot environment, no parts of the file system are unmounted. (BZ#1059118) All bind97 users are advised to upgrade to these updated Linux Distribution Packages, which contain backported patches to correct these issues. After installing the update, the BIND daemon (named) will be restarted automatically.

Affected Versions:

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
