Important: redis:6 security update

Published Jul 29, 2025 · Updated Jul 29, 2025

Summary

Redis is an advanced key-value store. It is often referred to as a data-structure server since keys can contain strings, hashes, lists, sets, and sorted sets. For performance, Redis works with an in-memory data set. You can persist it either by dumping the data set to disk every once in a while, or by appending each command to a log.

Security Fix(es):

* redis: Redis Unauthenticated Denial of Service (CVE-2025-48367)

* redis: Redis Hyperloglog Out-of-Bounds Write Vulnerability (CVE-2025-32023)
