Red Hat: 2012:1365-01: bind: Important Advisory
Summary
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.
