Synopsis

Background

Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache and message broker.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
dev-db/redis	< 6.0.12	>= 5.0.12	All supported architectures

Description

It was discovered that there were a number of integer overflow issues in Redis.

Impact

A remote attacker, able to connect to a Redis instance, could send a malicious crafted large request possibly resulting in the execution of arbitrary code with the privileges of the process or a Denial of Service condition.

Workaround

There is no known workaround at this time.
