redis vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 19.04
- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS

Summary:

Several security issues were fixed in Redis.

Software Description:
- redis: Persistent key-value database with network interface

Details:

It was discovered that Redis incorrectly handled the hyperloglog data structure.
An attacker could use this issue to cause Redis to crash, resulting in a denial
of service, or possibly execute arbitrary code.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 19.04:
  redis                           5:5.0.3-4ubuntu0.1
  redis-tools                     5:5.0.3-4ubuntu0.1

Ubuntu 18.04 LTS:
  redis                           5:4.0.9-1ubuntu0.2
  redis-tools                     5:4.0.9-1ubuntu0.2

Ubuntu 16.04 LTS:
  redis-tools                     2:3.0.6-1ubuntu0.4

In general, a standard system update will make all the necessary changes.
