CVE-2021-29478

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.
