Score breakdown

Buffer overflow in redis-cli of Redis before 4.0.10 and 5.x before 5.0 RC3 allows an attacker to achieve code execution and escalate to higher privileges via a crafted command line. NOTE: It is unclear whether there are any common situations in which redis-cli is used with, for example, a -h (aka hostname) argument from an untrusted source.

From the Ubuntu Security Team

It was discovered that Redis incorrectly handled certain arguments. An attacker could possibly use this issue to execute arbitrary code.
