CVE-2015-4620

CVSS v2.0

7.8

High

VectorAV:N/AC:L/Au:N/C:N/I:N/A:C
Name of the Vulnerable Software and Affected Versions ISC BIND versions 9.7.x through 9.9.x before 9.9.7-P1 ISC BIND versions 9.10.x before 9.10.2-P2
Description The issue allows remote attackers to cause a denial of service by constructing crafted zone data and then making a query for a name in that zone. This occurs when the software is configured as a recursive resolver with DNSSEC validation, leading to a REQUIRE assertion failure and daemon exit.
Recommendations For versions 9.7.x through 9.9.x before 9.9.7-P1, update to version 9.9.7-P1 or later. For versions 9.10.x before 9.10.2-P2, update to version 9.10.2-P2 or later.
