CVE-2015-4620
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)…
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 38.8%, higher than 99% of all known CVEs. Patch or mitigate before the next change window.
Description
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.
