CVE-2021-32626 (CNNVD-202110-135)
中文标题:
Redis Labs Redis 缓冲区错误漏洞
英文标题:
Lua scripts can overflow the heap-based Lua stack in Redis
漏洞描述
中文描述:
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 存在缓冲区错误漏洞，在Redis中执行特别制作的Lua脚本可能会导致基于堆的Lua堆栈溢出，这可能导致堆损坏，并可能导致远程代码执行。从2.6版本开始，所有支持Lua脚本的Redis版本都存在该漏洞。
英文描述:
Redis is an open source, in-memory database that persists on disk. In affected versions specially crafted Lua scripts executing in Redis can cause the heap-based Lua stack to be overflowed, due to incomplete checks for this condition. This can result with heap corruption and potentially remote code execution. This problem exists in all versions of Redis with Lua scripting support, starting from 2.6. The problem is fixed in versions 6.2.6, 6.0.16 and 5.0.14. For users unable to update an additional workaround to mitigate the problem without patching the redis-server executable is to prevent users from executing Lua scripts. This can be done using ACL to restrict EVAL and EVALSHA commands.
