Redis: Remote code execution

Background

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

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.

Resolution

All Redis 5.x users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=dev-db/redis-5.0.12"

All Redis 6.x users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=dev-db/redis-6.0.12"
