-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Important: redis:5 security update Advisory ID: RHSA-2021:3944-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2021:3944 Issue date: 2021-10-20 CVE Names: CVE-2021-32626 CVE-2021-32627 CVE-2021-32628 CVE-2021-32675 CVE-2021-32687 CVE-2021-41099 ==================================================================== 1. Summary: An update for the redis:5 module is now available for Red Hat Enterprise Linux 8.2 Extended Update Support. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux AppStream EUS (v. 8.2) - aarch64, noarch, ppc64le, s390x, x86_64 3. Description: 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: Lua scripts can overflow the heap-based Lua stack (CVE-2021-32626) * redis: Integer overflow issue with Streams (CVE-2021-32627) * redis: Integer overflow bug in the ziplist data structure (CVE-2021-32628) * redis: Denial of service via Redis Standard Protocol (RESP) request (CVE-2021-32675) * redis: Integer overflow issue with intsets (CVE-2021-32687) * redis: Integer overflow issue with strings (CVE-2021-41099) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section. 4.
