+bind: fix for CVE-2012-3817
+
+Upstream-Status: Backport
+
+ISC BIND 9.4.x, 9.5.x, 9.6.x, and 9.7.x before 9.7.6-P2; 9.8.x before 9.8.3-P2;
+9.9.x before 9.9.1-P2; and 9.6-ESV before 9.6-ESV-R7-P2, when DNSSEC validation
+is enabled, does not properly initialize the failing-query cache, which allows
+remote attackers to cause a denial of service (assertion failure and daemon exit)
+by sending many queries.
+
+http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2012-3817
+
+This patch is back-ported from bind-9.3.6-20.P1.el5_8.2.src.rpm package.
