Synopsis
========

A vulnerability in Redis could lead to remote code execution.

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
     -------------------------------------------------------------------
   1  dev-db/redis                 < 6.0.12                  >= 5.0.12
                                                             >= 6.0.12

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"
