CVE-2012-5166
ISC BIND 9.x before 9.7.6-P4, 9.8.x before 9.8.3-P4, 9.9.x before 9.9.1-P4, and 9.4-ESV and 9.6-ESV before 9.6-ESV-R7-P4 allows remote attackers to cause a denial of service (named daemon hang) via unspecified combinations of resource records.
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 32.7%, higher than 98% of all known CVEs. Patch or mitigate before the next change window.
