Título:	RedHat Update for bind RHSA-2017:1679-01
Resumen:	The remote host is missing an update for the 'bind'; package(s) announced via the referenced advisory.
Descripción:	Summary: The remote host is missing an update for the 'bind' package(s) announced via the referenced advisory. Vulnerability Insight: 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) Affected Software/OS: bind on Red Hat Enterprise Linux Desktop (v. 6), Red Hat Enterprise Linux Server (v. 6), Red Hat Enterprise Linux Workstation (v. 6) Solution: Please Install the Updated Packages. CVSS Score: 4.3 CVSS Vector: AV:N/AC:M/Au:N/C:N/I:P/A:N
