Fixed In Version: redis 6.2.6, redis 6.0.16, redis 5.0.14
Doc Type: If docs needed, set a value
Doc Text:
An integer overflow issue was found in redis. 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. This flaw allows a remote attacker to leak arbitrary contents of the heap or potentially trigger remote code execution. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

Description Pedro Sampaio 2021-10-05 17:59:10 UTC 
Redis is an open source, in-memory database that persists on disk. 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. The problem is fixed in Redis versions 6.2.6, 6.0.16 and 5.0.14. 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.

Comment 8 Tapas Jena 2021-10-11 16:14:36 UTC 
Analysis is complete for Ansible components and its found that neither the affected Redis version nor the affected functionality is in use in any Ansible components.Hence, marking all the Ansible components as not affected.
