The vulnerability involves changing the default set-max-intset-entries configuration value,
creating a large set key that consists of integer values and using the COPY command to duplicate
it.
The integer overflow bug exists in all versions of Redis starting with 2.6, where it could result
with a corrupted RDB or DUMP payload, but not exploited through COPY (which did not exist before 6.2).");
