QID 239733: Red Hat Update for redis:6 (RHSA-2021:3945)

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)
