Description

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 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. (CVE-2011-4313)

Users of bind97 are advised to upgrade to these updated packages, which resolve this issue. After installing the update, the BIND daemon (named) will be restarted automatically.
