Important: redis:5 security update
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: Heap buffer overflow in HyperLogLog triggered by malicious client (CVE-2019-10192)
-
redis: Stack buffer overflow in HyperLogLog triggered by malicious client (CVE-2019-10193)
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.
