RHSA-2021:3945: Important: redis:6 security update
First published: Wed Oct 20 2021(Updated: )
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.<br>Security Fix(es):<br><li> redis: Lua scripts can overflow the heap-based Lua stack (CVE-2021-32626)</li> <li> redis: Integer overflow issue with Streams (CVE-2021-32627)</li> <li> redis: Integer overflow bug in the ziplist data structure (CVE-2021-32628)</li> <li> redis: Denial of service via Redis Standard Protocol (RESP) request (CVE-2021-32675)</li> <li> redis: Integer overflow issue with intsets (CVE-2021-32687)</li> <li> redis: Integer overflow issue with strings (CVE-2021-41099)</li> 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.
