Red Hat Product Security has rated this update as having a security impact of Moderate. 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.
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) :
* It was found that the lightweight resolver protocol implementation in BIND could enter an infinite recursion and crash when asked to resolve a query name which, when combined with a search list entry, exceeds the maximum allowable length. A remote attacker could use this flaw to crash lwresd or named when using the 'lwres' statement in named.conf. (CVE-2016-2775)
