Detail
Problem Description: Updated bind packages that fix one security issue are now available for Red Hat Enterprise Linux 4. The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux Desktop version 4 - i386, x86_64 Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64 3. 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. It was discovered that named did not invalidate previously cached SIG 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) All BIND users are advised to upgrade to these updated packages, which contain a backported patch to resolve this issue. After installing the update, the BIND daemon (named) will be restarted automatically. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/docs/DOC-11259 5. Bugs fixed (http://bugzilla.redhat.com/): 658974 - CVE-2010-3613 bind: failure to clear existing RRSIG records when a NO DATA is negatively cached could DoS named |

| Description: | 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. | ||
