| Description: | The Berkeley Internet Name Domain (BIND) is an implementation of the DomainName System (DNS) protocols. It contains a DNS server (named), a resolverlibrary with routines for applications to use when interfacing with DNS,and tools for verifying that the DNS server is operating correctly.These packages contain version 9.7 of the BIND suite.A denial of service flaw was found in the way BIND handled queries forNSEC3-signed zones. A remote attacker could use this flaw against anauthoritative name server that served NCES3-signed zones by sending aspecially 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 ofbind97 shipped in Red Hat Enterprise Linux 5. This issue is being addressedhowever to assure it is not introduced in future builds of bind97 (possiblybuilt 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 theROOTDIR variable when shutting down the named daemon. As a consequence,some parts of the file system that are mounted when using bind97 in achroot environment were unmounted on daemon shut down, even if bind97 wasnot running in a chroot environment. With this update, the initscript hasbeen fixed to check for the existence of the ROOTDIR variable whenunmounting some parts of the file system on named daemon shut down. Now,when shutting down bind97 that is not running in a chroot environment, noparts of the file system are unmounted. (BZ#1059118)All bind97 users are advised to upgrade to these updated packages, whichcontain backported patches to correct these issues. After installing theupdate, the BIND daemon (named) will be restarted automatically. |
