How to fix?

There is no fixed version for RHEL:7 redis.

NVD Description

Note: Versions mentioned in the description apply only to the upstream redis package and not the redis package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

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.
