- Summary
- CVE-2022-3924 affecting package bind for versions less than 9.16.37-2
- Details
-
This issue can affect BIND 9 resolvers with
stale-answer-enable yes;that also make use of the optionstale-answer-client-timeout, configured with a value greater than zero.If the resolver receives many queries that require recursion, there will be a corresponding increase in the number of clients that are waiting for recursion to complete. If there are sufficient clients already waiting when a new client query is received so that it is necessary to SERVFAIL the longest waiting client (see BIND 9 ARM
recursive-clientslimit and soft quota), then it is possible for a race to occur between providing a stale answer to this older client and sending an early timeout SERVFAIL, which may cause an assertion failure. This issue affects BIND 9 versions 9.16.12 through 9.16.36, 9.18.0 through 9.18.10, 9.19.0 through 9.19.8, and 9.16.12-S1 through 9.16.36-S1. - References
