Description:

Please see this blog posting for information on ISC standardizing of security issue evaluation and why this bug didn't merit a Security Advisory.

This is what was put in the release notes:

If BIND, acting as a DNSSEC validating server, has two or more trust anchors configured in named.conf for the same zone (such as example.com) and the response for a record in that zone from the authoritative server includes a bad signature, the validating server will crash while trying to validate that query.

Workarounds:

Upgrade to 9.7.2-P3 or later. 

Active exploits:

None known at this time.
