CentOS Errata and Security Advisory CESA-2017:1095
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.
