CVE-2018-12326 Explained : Impact and Mitigation

A vulnerability known as buffer overflow has been discovered in the redis-cli program of Redis versions earlier than 4.0.10 and 5.x prior to 5.0 RC3. This flaw can be exploited by an attacker to execute arbitrary code and raise their privileges by sending a specially crafted command line input. It should be noted that it is uncertain whether there are any typical scenarios in which redis-cli is utilized with an untrusted source providing a -h (hostname) argument.
