A security issue has been reported in Redis, which can be exploited by malicious, local users to perform certain actions with escalated privileges.

The security issue is caused due to the application using a temporary file in an insecure manner, which can be exploited to e.g. overwrite arbitrary files via symlink attacks.

The security issue is reported in version 2.4.18. Other versions may also be affected.

Update to version 2.6.8.
