Red Hat Security Advisory: bind security update Security Advisory secalert@redhat.com Red Hat Security Response Team RHSA-2012:1268 Final 1 1 2012-09-14T09:20:00Z Current version 2012-09-14T09:20:00Z 2012-09-14T09:20:00Z Red Hat rhsa-to-cvrf 1.0.1484 2012-09-14T09:30:02Z Updated bind packages that fix one security issue are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. 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) Users of bind are advised to upgrade to these updated packages, which correct this issue. After installing the update, the BIND daemon (named) will be restarted automatically.
