Incorrect operator (CWE-480) in the FetchSnapshot RPC handler
in Apache Kafka from 2.8.0 before 4.2.2, and from 4.3.0 before 4.3.2
on all platforms allows an authenticated attacker with
CLUSTER_ACTION privilege to cause a denial of service
(controller process termination) via a crafted
FetchSnapshotRequest with an empty topics array or a topic
with no partitions.
Users are recommended to upgrade to version 4.2.2, 4.3.2, or
4.4.0, which fix this issue. Users on unsupported branches
(4.1.x and earlier) should upgrade to 4.2.2 or later.
