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.
