Vulnerability Title
Integer overflow that can lead to heap overflow in redis-cli, redis-sentinel on some platforms
Vulnerability Description
Redis is an open source, in-memory database that persists on disk. The redis-cli command line tool and redis-sentinel service may be vulnerable to integer overflow when parsing specially crafted large multi-bulk network replies. This is a result of a vulnerability in the underlying hiredis library which does not perform an overflow check before calling the calloc() heap allocation function. This issue only impacts systems with heap allocators that do not perform their own overflow checks. Most modern systems do and are therefore not likely to be affected. Furthermore, by default redis-sentinel uses the jemalloc allocator which is also not vulnerable. The problem is fixed in Redis versions 6.2.6, 6.0.16 and 5.0.14.

Vulnerability Title
Redis Labs Redis 安全漏洞
Vulnerability Description
Redis Labs Redis是美国Redis Labs公司的一套开源的使用ANSI C编写、支持网络、可基于内存亦可持久化的日志型、键值（Key-Value）存储数据库，并提供多种语言的API。 Redis 存在安全漏洞，该漏洞源于命令行工具redis-cli和redis-sentinel服务在解析专门制作的大型多批量网络回复时可能容易出现整数溢出。
