The remote Amazon Linux AMI host is missing a security update.
Package updates are available for Amazon Linux AMI that fix the
following vulnerabilities :
The Berkeley Internet Name Domain (BIND) is an implementation of the
Domain Name System (DNS) protocols. BIND includes a DNS server
a resolver library (routines for applications to use when
interfacing with DNS)
and tools for verifying that the DNS server is
A flaw was discovered in the way BIND handled certain DNS queries,
which caused it to cache an invalid record. A remote attacker could
use this flaw to send repeated queries for this invalid record,
causing the resolvers to exit unexpectedly due to a failed assertion.
From CVE-2011-4313 :
query.c in ISC BIND 9.0.x through 9.6.x, 9.4-ESV through 9.4-ESV-R5,
9.6-ESV through 9.6-ESV-R5, 9.7.0 through 9.7.4, 9.8.0 through 9.8.1,
and 9.9.0a1 through 9.9.0b1 allows remote attackers to cause a denial
of service (assertion failure and named exit) via unknown vectors
related to recursive DNS queries, error logging, and the caching of an
invalid record by the resolver.

Run 'yum upgrade bind*' to upgrade your system. After installing the
update, the bind daemon (named) will restart automatically.
