CVE-2022-3488
Last modified
CVE-2022-3488 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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.. EPSS estimates a 19.05% chance of exploitation in the next 30 days.
