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

The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

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.

It was discovered that named did not invalidate previously cached RRSIG records when adding an NCACHE record for the same entry to the cache. A remote attacker allowed to send recursive DNS queries to named could use this flaw to crash named. (CVE-2010-3613)

A flaw was found in the DNSSEC validation code in named. If named had multiple trust anchors configured for a zone, a response to a request for a record in that zone with a bad signature could cause named to crash. (CVE-2010-3762)

It was discovered that, in certain cases, named did not properly perform DNSSEC validation of an NS RRset for zones in the middle of a DNSKEY algorithm rollover. This flaw could cause the validator to incorrectly determine that the zone is insecure and not protected by DNSSEC. (CVE-2010-3614)

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

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'.

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

According to its self-reported version number, the remote installation of BIND is affected by multiple vulnerabilities :

  - A flaw exists that allows access to a cache via     recursion even though the ACL disallows it. Note that     this only occurs if BIND is operating as both an     authoritative and recursive name server in the same     view.

  - If BIND, acting as a DNSSEC validating server, has two     or more trust anchors configured in named.conf for the     same zone and the response for a record in that zone     from the authoritative server includes a bad signature,     the validating server will crash while trying to     validate that query.

It was discovered that Bind incorrectly handled certain bad signatures if multiple trust anchors existed for a single zone. A remote attacker could use this flaw to cause Bind to stop responding, resulting in a denial of service. This issue only affected Ubuntu 8.04 LTS and 10.04 LTS. (CVE-2010-3762)

Frank Kloeker and Michael Sinatra discovered that Bind incorrectly handled certain very large RRSIG RRsets included in negative responses. A remote attacker could use this flaw to cause Bind to stop responding, resulting in a denial of service. (CVE-2011-1910).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote host is affected by the vulnerability described in GLSA-201206-01 (BIND: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in BIND. Please review the       CVE identifiers referenced below for details.
  Impact :

    The vulnerabilities allow remote attackers to cause a Denial of Service       (daemon crash) via a DNS query, to bypass intended access restrictions,       to incorrectly cache a ncache entry and a rrsig for the same type and to       incorrectly mark zone data as insecure.
  Workaround :

    There is no known workaround at this time.

a. Service Location Protocol daemon DoS

   This patch fixes a denial-of-service vulnerability in    the Service Location Protocol daemon (SLPD). Exploitation of this    vulnerability could cause SLPD to consume significant CPU    resources.

   VMware would like to thank Nicolas Gregoire and US CERT for    reporting this issue to us.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2010-3609 to this issue.

b. Service Console update for bind

   This patch updates the bind-libs and bind-utils RPMs to version    9.3.6-4.P1.el5_5.3, which resolves multiple security issues.

   The Common Vulnerabilities and Exposures project (cve.mitre.org)    has assigned the names CVE-2010-3613, CVE-2010-3614, and    CVE-2010-3762 to these issues.

c. Service Console update for pam

   This patch updates the pam RPM to pam_0.99.6.2-3.27.5437.vmw,    which resolves multiple security issues with PAM modules.

   The Common Vulnerabilities and Exposures project (cve.mitre.org)    has assigned the names CVE-2010-3316, CVE-2010-3435, and    CVE-2010-3853 to these issues.

d. Service Console update for rpm, rpm-libs, rpm-python, and popt

   This patch updates rpm, rpm-libs, and rpm-python RPMs to    4.4.2.3-20.el5_5.1, and popt to version 1.10.2.3-20.el5_5.1,    which resolves a security issue.

   The Common Vulnerabilities and Exposures project (cve.mitre.org)    has assigned the name CVE-2010-2059 to this issue.

Multiple vulnerabilities were discovered and corrected in bind :

named in ISC BIND 9.6.2 before 9.6.2-P3, 9.6-ESV before 9.6-ESV-R3, and 9.7.x before 9.7.2-P3 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 (daemon crash) via a query for cached data (CVE-2010-3613).

named in ISC BIND 9.x before 9.6.2-P3, 9.7.x before 9.7.2-P3, 9.4-ESV before 9.4-ESV-R4, and 9.6-ESV before 9.6-ESV-R3 does not properly determine the security status of an NS RRset during a DNSKEY algorithm rollover, which might allow remote attackers to cause a denial of service (DNSSEC validation error) by triggering a rollover (CVE-2010-3614).

ISC BIND before 9.7.2-P2, when DNSSEC validation is enabled, 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 (daemon crash) via a DNS query (CVE-2010-3762).

Packages for 2009.0 are provided as of the Extended Maintenance Program. Please visit this link to learn more:
http://store.mandriva.com/product_info.php?cPath=149&amp;products_id=4 90

The updated packages for Corporate Server 4.0 has been patched to address these issues.

The updated packages for Mandriva Linux 2009.0, 2010.0 and Mandriva Linux Enterprise Server 5.1 has been upgraded to bind-9.6.2-P3 and patched to address the CVE-2010-3762 security issue.

The updated packages for Mandriva Linux 2010.1 has been upgraded to bind-9.7.2-P3 which is not vulnerable to these issues.

ISC BIND before 9.7.2-P2, when DNSSEC validation is enabled, 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 (daemon crash) via a DNS query

It was discovered that named did not invalidate previously cached RRSIG records when adding an NCACHE record for the same entry to the cache. A remote attacker allowed to send recursive DNS queries to named could use this flaw to crash named. (CVE-2010-3613)

A flaw was found in the DNSSEC validation code in named. If named had multiple trust anchors configured for a zone, a response to a request for a record in that zone with a bad signature could cause named to crash. (CVE-2010-3762)

It was discovered that, in certain cases, named did not properly perform DNSSEC validation of an NS RRset for zones in the middle of a DNSKEY algorithm rollover. This flaw could cause the validator to incorrectly determine that the zone is insecure and not protected by DNSSEC. (CVE-2010-3614)

After installing the update, the BIND daemon (named) will be restarted automatically.

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

  - bind
  - pam
  - popt
  - rpm
  - rpm-libs
  - rpm-python
  - Service Location Protocol daemon (SLPD)

The remote host is running BIND, and open source name server.

Versions of BIND 9.7 earlier than 9.7.2 P2 are potentially affected by multiple vulnerabilities :

  - If BIND, acting as a DNSSEC validating server, has two or more trust anchors configured in named.conf for the same zone and the response for a record in that zone from the authoritative server includes a bad signature, the validating server will crash while trying to validate the query.

  - A flaw exists that allows access to a cache via recursion even if the ACL disallows it.
