"bind was updated to fix two security issues.

These security issues were fixed :

  - CVE-2015-1349: Named in ISC BIND 9.7.0 through 9.9.6
    before 9.9.6-P2 and 9.10.x before 9.10.1-P2, when DNSSEC
    validation and the managed-keys feature are enabled,
    allowed remote attackers to cause a denial of service
    (assertion failure and daemon exit, or daemon crash) by
    triggering an incorrect trust-anchor management scenario
    in which no key is ready for use (bsc#918330).

  - CVE-2015-4620: Fixed resolver crash when validating
    (bsc#936476).

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
