Type/Severity
Security Advisory: Important
Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Topic
An update for the redis:5 module is now available for Red Hat Enterprise Linux 8.1 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.
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)
