===================================================================== Red Hat Security Advisory
Synopsis: Important: bind security update Advisory ID: RHSA-2016:0601-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2016-0601.html Issue date: 2016-04-06 CVE Names: CVE-2016-1285 CVE-2016-1286 =====================================================================
1. Summary:
An update for bind is now available for Red Hat Enterprise Linux 6.2 Advanced Update Support.
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 Server AUS (v. 6.2) - x86_64 Red Hat Enterprise Linux Server Optional AUS (v. 6.2) - 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 parsed signature records for DNAME records. By sending a specially crafted query, a remote attacker could use this flaw to cause named to crash. (CVE-2016-1286)
* A denial of service flaw was found in the way BIND processed certain control channel input. A remote attacker able to send a malformed packet to the control channel could use this flaw to cause named to crash. (CVE-2016-1285)
Red Hat would like to thank ISC for reporting these issues.
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/):
