A flaw was found in Bind, where a resolver crash is possible. When stale cache and stale answers are enabled, the option stale-answer-client-timeout is set to a positive integer, and the resolver receives an RRSIG query.

Mitigation

Setting stale-answer-client-timeout to 0 or to off/disabled will prevent BIND from crashing due to this issue.
