An as-yet unidentified network event caused BIND 9 resolvers to cache an invalid record, subsequent queries for which could crash the resolvers with an assertion failure.

Furthermore, AIX BIND 9.4.1 is affected by the following three security vulnerabilities: CVE-2010-0382 - ISC BIND Out-Of-Bailwick Data Handling Error CVE-2010-0097 - ISC BIND Improper DNSSEC NSEC and NSEC3 Record CVE-2009-0025 - BIND OpenSSL DSA_do_verify and EVP_VerifyFinal.

Some vulnerabilities were discovered and corrected in bind :

The original fix for CVE-2009-4022 was found to be incomplete. BIND was incorrectly caching certain responses without performing proper DNSSEC validation. CNAME and DNAME records could be cached, without proper DNSSEC validation, when received from processing recursive client queries that requested DNSSEC records but indicated that checking should be disabled. A remote attacker could use this flaw to bypass the DNSSEC validation check and perform a cache poisoning attack if the target BIND server was receiving such client queries (CVE-2010-0290).

There was an error in the DNSSEC NSEC/NSEC3 validation code that could cause bogus NXDOMAIN responses (that is, NXDOMAIN responses for records proven by NSEC or NSEC3 to exist) to be cached as if they had validated correctly, so that future queries to the resolver would return the bogus NXDOMAIN with the AD flag set (CVE-2010-0097).

ISC BIND 9.0.x through 9.3.x, 9.4 before 9.4.3-P5, 9.5 before 9.5.2-P2, 9.6 before 9.6.1-P3, and 9.7.0 beta handles out-of-bailiwick data accompanying a secure response without re-fetching from the original source, which allows remote attackers to have an unspecified impact via a crafted response, aka Bug 20819. NOTE: this vulnerability exists because of a regression during the fix for CVE-2009-4022 (CVE-2010-0382).

Packages for 2008.0 are provided for Corporate Desktop 2008.0 customers.

Additionally BIND has been upgraded to the latest patch release version.

Updated bind packages that fix two security issues are now available for Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

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 BIND DNSSEC NSEC/NSEC3 validation code. If BIND was running as a DNSSEC-validating resolver, it could incorrectly cache NXDOMAIN responses, as if they were valid, for records proven by NSEC or NSEC3 to exist. A remote attacker could use this flaw to cause a BIND server to return the bogus, cached NXDOMAIN responses for valid records and prevent users from retrieving those records (denial of service). (CVE-2010-0097)

The original fix for CVE-2009-4022 was found to be incomplete. BIND was incorrectly caching certain responses without performing proper DNSSEC validation. CNAME and DNAME records could be cached, without proper DNSSEC validation, when received from processing recursive client queries that requested DNSSEC records but indicated that checking should be disabled. A remote attacker could use this flaw to bypass the DNSSEC validation check and perform a cache poisoning attack if the target BIND server was receiving such client queries.
(CVE-2010-0290)

All BIND users are advised to upgrade to these updated packages, which contain a backported patch to resolve these issues. After installing the update, the BIND daemon (named) will be restarted automatically.

Several cache-poisoning vulnerabilities have been discovered in BIND.
These vulnerabilities apply only if DNSSEC validation is enabled and trust anchors have been installed, which is not the default.

The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2010-0097     BIND does not properly validate DNSSEC NSEC records,     which allows remote attackers to add the Authenticated     Data (AD) flag to a forged NXDOMAIN response for an     existing domain.

  - CVE-2010-0290     When processing crafted responses containing CNAME or     DNAME records, BIND is subject to a DNS cache poisoning     vulnerability, provided that DNSSEC validation is     enabled and trust anchors have been installed.

  - CVE-2010-0382     When processing certain responses containing     out-of-bailiwick data, BIND is subject to a DNS cache     poisoning vulnerability, provided that DNSSEC validation     is enabled and trust anchors have been installed.

In addition, this update introduce a more conservative query behavior in the presence of repeated DNSSEC validation failures, addressing the 'roll over and die' phenomenon. The new version also supports the cryptographic algorithm used by the upcoming signed ICANN DNS root (RSASHA256 from RFC 5702), and the NSEC3 secure denial of existence algorithm used by some signed top-level domains.

This update is based on a new upstream version of BIND 9, 9.6-ESV-R1.
Because of the scope of changes, extra care is recommended when installing the update. Due to ABI changes, new Debian packages are included, and the update has to be installed using 'apt-get dist-upgrade' (or an equivalent aptitude command).

The remote VMware ESX / ESXi host is missing a security-related patch.
It is, therefore, affected by multiple vulnerabilities, including remote code execution vulnerabilities, in several components and third-party libraries :

  - libpng
  - VMnc Codec
  - vmrun
  - VMware Remote Console (VMrc)
  - VMware Tools
  - vmware-authd
