3. 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: Heap buffer overflow in HyperLogLog triggered by malicious client
(CVE-2019-10192)

* redis: Heap corruption in lua_cmsgpack.c (CVE-2018-11218)

* redis: Integer overflow in lua_struct.c:b_unpack() (CVE-2018-11219)

* redis: Code execution in redis-cli via crafted command line arguments
(CVE-2018-12326)

For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE
