Description:
 Redis is an open source (BSD licensed), in-memory data structure store,
 used as a database, cache, and message broker. An integer overflow bug in
 Redis 6.2 before 6.2.3 could be exploited to corrupt the heap and
 potentially result with remote code execution. Redis 6.0 and earlier are
 not directly affected by this issue. The problem is fixed in version 6.2.3.
 An additional workaround to mitigate the problem without patching the
 `redis-server` executable is to prevent users from modifying the
 `set-max-intset-entries` configuration parameter. This can be done using
 ACL to restrict unprivileged users from using the `CONFIG SET` command.
