Scientific Linux Security Update : bind97 on SL5.x i386/x86_64
Low Nessus Plugin ID 78416
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionA 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 Scientific 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.
After installing the update, the BIND daemon (named) will be restarted automatically.
SolutionUpdate the affected packages.
