Topic

An update for rh-redis32-redis is now available for Red Hat Software Collections.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

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)
