CVE-2010-0213: ISC BIND

Low severity, CVSS 2.6. EPSS: 6.5% chance of exploitation in the next 30 days.

BIND 9.7.1 and 9.7.1-P1, when a recursive validating server has a trust anchor that is configured statically or via DNSSEC Lookaside Validation (DLV), allows remote attackers to cause a denial of service (infinite loop) via a query for an RRSIG record whose answer is not in the cache, which causes BIND to repeatedly send RRSIG queries to the authoritative servers.

Affected products

• ISC BIND: version 9.7.1 only
