Detailsinfo

A vulnerability was found in ISC BIND 9.7.1/9.7.1-p1 (Domain Name Software). It has been rated as problematic. Affected by this issue is an unknown code of the component DNSSEC Lookaside Validation. The manipulation as part of a RRSIG Request leads to a data processing vulnerability. Using CWE to declare the problem leads to CWE-19. Impacted is availability. CVE summarizes:

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.
