Redis-6.2.x version official release notes (with Google translation) [continuous update]

I. Introduction

This article simply translates the official release notes of Redis version 6.2.x, and will not make any changes to the content of the release notes. If readers have any objections, they can go to the relevant official Redis web pages to check. Translation tools may not be 100% accurate. People who are good at English don’t complain. Everyone is a person with poor English. I hope you can understand and tolerate . Of course, the author will make appropriate modifications to certain phrases and sentences that are difficult to pronounce. At the same time, the author also wrote another blog about the 7.0.x version release notes - " Redis-7.0.x version official release notes (with Google translation) [continuous update] ", readers can read it by themselves.

The author's translation tool uses " Ciji Translation ", the official website: https://hcfy.app/ , the advantage is that it supports Google Translate and other translations, such as DeepL, Baidu, Youdao, etc., and supports full-text translation of web pages. Both Chinese and English are displayed. The disadvantage is that there is a fee, but it is not expensive, 45 RMB a year, 5 RMB a month, pay with WX, just use your email to register an account. Both Google Chrome and Firefox can install the "Word Translator" plug-in, but Safari, Microsoft Edge and IE have not tried it. 注意: Google Translate has withdrawn from the Chinese market. If you want to use the Google Translate function, you need to use that method. I won’t say more, and if you say more, the article will fail the review .

The installation and deployment blogs related to Redis are as follows:

Docker installs the latest Redis6 (redis-6.2.7) (refer to official documents)

Docker installs the latest stable version of Redis7 (redis-7.0.5) (refers to official documents)

Write the best latest Redis6 (redis-6.2.7) on the cloud server Centos7 installation and deployment tutorial (refer to official documents)

write the best latest stable version of Redis7 (redis-7.0.5) in the cloud server Centos7 installation and deployment tutorial (refer to official documents)

Integer overflow in STRALGO LCS command (CVE-2021-29477):
STRALGO LCS 命令中的整数溢出 (CVE-2021-29477)
An integer overflow bug in Redis version 6.0 or newer could be exploited using the STRALGO LCS command to corrupt the heap and potentially result in remote code execution. The integer overflow bug exists in all versions of Redis starting with 6.0.

Integer overflow in COPY command for large intsets (CVE-2021-29478):
大型 intset 的 COPY 命令中的整数溢出 (CVE-2021-29478)
An integer overflow bug in Redis 6.2 could be exploited to corrupt the heap and potentially result with remote code execution. The vulnerability involves changing the default set-max-intset-entries configuration value, creating a large set key that consists of integer values and using the COPY command to duplicate it. The integer overflow bug exists in all versions of Redis starting with 2.6, where it could result with a corrupted RDB or DUMP payload, but not exploited through COPY (which did not exist before 6.2).
Redis 6.2 中的整数溢出错误可被利用来破坏堆并可能导致远程代码执行。该漏洞涉及更改默认的 set-max-intset-entries 配置值，创建一个由整数值组成的大集合键并使用 COPY 命令复制它。整数溢出错误存在于从 2.6 开始的所有 Redis 版本中，它可能导致损坏的 RDB 或 DUMP 负载，但无法通过 COPY（在 6.2 之前不存在）利用。

Redis 6.2.0 GA Released Tue Feb 22 14:00:00 IST 2021 (Redis 6.2.0 GA Released Tue Feb 22 14:00:00 IST 2021)

Upgrade urgency: SECURITY if you use 32bit build of redis (see bellow), MODERATE if you used earlier versions of Redis 6.2, LOW otherwise.
升级紧迫性：如果您使用 32 位版本的 Redis（见下文），则为安全；如果您使用 Redis 6.2 的早期版本，则为中等；否则为低。

Integer overflow on 32-bit systems (CVE-2021-21309):
32 位系统上的整数溢出 (CVE-2021-21309)
Redis 4.0 or newer uses a configurable limit for the maximum supported bulk input size. By default, it is 512MB which is a safe value for all platforms. If the limit is significantly increased, receiving a large request from a client may trigger several integer overflow scenarios, which would result with buffer overflow and heap corruption.
Redis 4.0 或更高版本对支持的最大批量输入大小使用可配置限制。默认情况下，它是 512MB，这是所有平台的安全值。如果限制显着增加，从客户端接收大请求可能会触发多个整数溢出场景，这将导致缓冲区溢出和堆损坏。

Introduction to the Redis 6.2 release（Redis 6.2 版本介绍）

This release is the first significant Redis release managed by the core team under the new project governance model.
此版本是核心团队在新项目治理模型下管理的第一个重要 Redis 版本。

Redis 6.2 includes many new commands and improvements, but no big features. It mainly makes Redis more complete and addresses issues that have been requested by many users frequently or for a long time.
Redis 6.2 包含许多新命令和改进，但没有大的功能。主要是让Redis更加完善，解决了很多用户经常或者长时间要求的问题。

Many of these changes were not eligible for 6.0.x for several reasons:
由于以下几个原因，其中许多更改不符合 6.0.x 的条件：

They are not backward compatible, which is always the case with new or extended commands (that cannot be replicated to an older replica).

They require a longer release-candidate test cycle.
