Synopsis: Important: bind security and bug fix update Advisory ID: RHSA-2017:1679-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2017:1679 Issue date: 2017-07-05 CVE Names: CVE-2017-3142 CVE-2017-3143 =====================================================================
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 flaw was found in the way BIND handled TSIG authentication for dynamic updates. A remote attacker able to communicate with an authoritative BIND server could use this flaw to manipulate the contents of a zone, by forging a valid TSIG or SIG(0) signature for a dynamic update request. (CVE-2017-3143)
* A flaw was found in the way BIND handled TSIG authentication of AXFR requests. A remote attacker, able to communicate with an authoritative BIND server, could use this flaw to view the entire contents of a zone by sending a specially constructed request packet. (CVE-2017-3142)
Red Hat would like to thank Internet Systems Consortium for reporting these issues. Upstream acknowledges Clement Berthaux (Synacktiv) as the original reporter of these issues.
Bug Fix(es):
* ICANN is planning to perform a Root Zone DNSSEC Key Signing Key (KSK) rollover during October 2017. Maintaining an up-to-date KSK, by adding the new root zone KSK, is essential for ensuring that validating DNS resolvers continue to function following the rollover. (BZ#1458234)
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/):
1466189 - CVE-2017-3142 bind: An error in TSIG authentication can permit unauthorized zone transfers 1466193 - CVE-2017-3143 bind: An error in TSIG authentication can permit unauthorized dynamic updates
