Description

Several remote vulnerabilities have been discovered in BIND, an implementation of the DNS protocol suite. The Common Vulnerabilities and Exposures project identifies the following problems :

  • CVE-2010-3762 When DNSSEC validation is enabled, BIND does not properly handle certain bad signatures if multiple trust anchors exist for a single zone, which allows remote attackers to cause a denial of service (server crash) via a DNS query.

  • CVE-2010-3614 BIND does not properly determine the security status of an NS RRset during a DNSKEY algorithm rollover, which may lead to zone unavailability during rollovers.

  • CVE-2010-3613 BIND does not properly handle the combination of signed negative responses and corresponding RRSIG records in the cache, which allows remote attackers to cause a denial of service (server crash) via a query for cached data.

In addition, this security update improves compatibility with previously installed versions of the bind9 package. As a result, it is necessary to initiate the update with 'apt-get dist-upgrade' instead of 'apt-get update'.
