USN-4061-1: Redis vulnerabilities

16 July 2019

Several security issues were fixed in Redis.



  • redis - Persistent key-value database with network interface


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
Ubuntu 18.04
Ubuntu 16.04

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