Red Hat: 2012:1110-01: 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 zero length resource data records.
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 crash or, possibly, disclose portions of
its memory. (CVE-2012-1667)
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.
