Red Hat Security Advisory: bind security update Security Advisory secalert@redhat.com Red Hat Security Response Team RHSA-2012:1365 Final 1 1 2012-10-12T19:37:00Z Current version 2012-10-12T19:37:00Z 2012-10-12T19:37:00Z Red Hat rhsa-to-cvrf 1.0.1484 2012-10-12T19:42:02Z Updated bind packages that fix two security issues are now available for Red Hat Enterprise Linux 4 Extended Life Cycle Support. The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links 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) A flaw was found in the way BIND handled certain combinations of resource records. A remote attacker could use this flaw to cause a recursive resolver, or an authoritative server in certain configurations, to lockup. (CVE-2012-5166) 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.
