Topic
An update for the redis:6 module is now available for Red Hat Enterprise Linux 8.
Red Hat Product Security has rated this update as having a security impact of Low. 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.
The following packages have been upgraded to a later upstream version: redis (6.2.7). (BZ#1999873)
Security Fix(es):
- redis: Code injection via Lua script execution environment (CVE-2022-24735)
- redis: Malformed Lua script can crash Redis (CVE-2022-24736)
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.

Vulnerability in the Oracle Banking Trade Finance product of Oracle Financial Services Applications (component: Infrastructure). The supported version that is affected is 14.5. Difficult to exploit vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Banking Trade Finance. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Banking Trade Finance accessible data as well as unauthorized access to critical data or complete access to all Oracle Banking Trade Finance accessible data. CVSS 3.1 Base Score 6.4 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:N).

Redis is an in-memory database that persists on disk. Prior to versions 6.2.7 and 7.0.0, an attacker attempting to load a specially crafted Lua script can cause NULL pointer dereference which will result with a crash of the redis-server process. The problem is fixed in Redis versions 7.0.0 and 6.2.7. An additional workaround to mitigate this problem without patching the redis-server executable, if Lua scripting is not being used, is to block access to `SCRIPT LOAD` and `EVAL` commands using ACL rules.
