RedHat: RHSA-2021-3945:01 Important: redis:6 security update
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: 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)
