Integer overflow issue with intsets
Impact
An integer overflow bug affecting all versions of Redis can be exploited to corrupt the heap and potentially be used to leak arbitrary contents of the heap or trigger remote code execution.
The vulnerability involves changing the default set-max-intset-entries configuration parameter to a very large value and constructing specially crafted commands to manipulate sets.
Patches
The problem is fixed in Redis versions 6.2.6, 6.0.16 and 5.0.14.
Workarounds
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.

This issue was discovered and reported by Pawel Wieczorkiewicz (Amazon Web Services).
