CVE-2015-4620 Bind vulnerability
Title: Bind vulnerability
Summary: Bind could be made to crash if it received specially crafted network
traffic.
Breno Silveira Soares discovered that Bind incorrectly handled certain
zone data when configured to perform DNSSEC validation. A remote attacker
could use this issue with specially crafted zone data to cause Bind to
crash, resulting in a denial of service.
Instructions: In general, a standard system update will make all the necessary changes.

name.c in named in ISC BIND 9.7.x through 9.9.x before 9.9.7-P1 and 9.10.x before 9.10.2-P2, when configured as a recursive resolver with DNSSEC validation, allows remote attackers to cause a denial of service (REQUIRE assertion failure and daemon exit) by constructing crafted zone data and then making a query for a name in that zone.
A flaw was found in the way BIND performed DNSSEC validation. An attacker able to make BIND (functioning as a DNS resolver with DNSSEC validation enabled) resolve a name in an attacker-controlled domain could cause named to exit unexpectedly with an assertion failure.
Statement: This issue did not affect the versions of bind packages as shipped with Red Hat Enterprise Linux 4 and 5. This i
