Synopsis: Important: bind security and bug fix update
Issue Date: 2012-09-14
CVE Numbers: CVE-2012-4244
—
The Berkeley Internet Name Domain (BIND) is an implementation of the Domain
Name System (DNS) protocols. BIND includes a DNS server (named); a resolver
library (routines for applications to use when interfacing with DNS); and
tools for verifying that the DNS server is operating correctly.
A flaw was found in the way BIND handled resource records with a large
RDATA value. A malicious owner of a DNS domain could use this flaw to
create specially-crafted DNS resource records, that would cause a recursive
resolver or secondary server to exit unexpectedly with an assertion
failure. (CVE-2012-4244)
This update also fixes the following bug:
* The bind-chroot-admin script, executed when upgrading the bind-chroot
package, failed to correctly update the permissions of the
/var/named/chroot/etc/named.conf file. Depending on the permissions of the
file, this could have prevented named from starting after installing
package updates. With this update, bind-chroot-admin correctly updates the
permissions and ownership of the file.
Users of bind are advised to upgrade to these updated packages, which
correct these issues. After installing the update, the BIND daemon (named)
will be restarted automatically.
