CVE-2018-5737
Deliberate exploitation of this condition could cause operational problems depending on the particular manifestation -- either degradation or denial of service.
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 10.4%, higher than 96% of all known CVEs. Patch or mitigate before the next change window.
Description
A problem with the implementation of the new serve-stale feature in BIND 9.12 can lead to an assertion failure in rbtdb.c, even when stale-answer-enable is off. Additionally, problematic interaction between the serve-stale feature and NSEC aggressive negative caching can in some cases cause undesirable behavior from named, such as a recursion loop or excessive logging. Deliberate exploitation of this condition could cause operational problems depending on the particular manifestation -- either degradation or denial of service. Affects BIND 9.12.0 and 9.12.1.
