CVE-2022-3488

HIGH

BIND 9.11.4-S1-9.11.37-S1 and 9.16.8-S1-9.16.36-S1 - Reachable Assertion via ECS Pseudo-Option Processing

Title source: llm
STIX 2.1

Description

Processing of repeated responses to the same query, where both responses contain ECS pseudo-options, but where the first is broken in some way, can cause BIND to exit with an assertion failure. 'Broken' in this context is anything that would cause the resolver to reject the query response, such as a mismatch between query and answer name. This issue affects BIND 9 versions 9.11.4-S1 through 9.11.37-S1 and 9.16.8-S1 through 9.16.36-S1.
