news 28 Posted April 20, 2017 -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: bind security update Advisory ID: RHSA-2017:1105-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2017:1105 Issue date: 2017-04-20 CVE Names: CVE-2017-3136 CVE-2017-3137 ===================================================================== 1. Summary: An update for bind is now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, 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. Security Fix(es): * A denial of service flaw was found in the way BIND handled a query response containing CNAME or DNAME resource records in an unusual order. A remote attacker could use this flaw to make named exit unexpectedly with an assertion failure via a specially crafted DNS response. (CVE-2017-3137) * A denial of service flaw was found in the way BIND handled query requests when using DNS64 with "break-dnssec yes" option. A remote attacker could use this flaw to make named exit unexpectedly with an assertion failure via a specially crafted DNS request. (CVE-2017-3136) Red Hat would like to thank ISC for reporting these issues. Upstream acknowledges Oleg Gorokhov (Yandex) as the original reporter of CVE-2017-3136. 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 After installing the update, the BIND daemon (named) will be restarted automatically. 5. Bugs fixed (https://bugzilla.redhat.com/): 1441125 - CVE-2017-3136 bind: Incorrect error handling causes assertion failure when using DNS64 with "break-dnssec yes;" 1441133 - CVE-2017-3137 bind: Processing a response containing CNAME or DNAME with unusual order can crash resolver 6.
