Redis allows out of bounds writes in hyperloglog commands leading to RCE

Redis is an open source, in-memory database that persists on disk. From 2.8 to before 8.0.3, 7.4.5, 7.2.10, and 6.2.19, an authenticated user may use a specially crafted string to trigger a stack/heap out of bounds write on hyperloglog operations, potentially leading to remote code execution. The bug likely affects all Redis versions with hyperloglog operations implemented. This vulnerability is fixed in 8.0.3, 7.4.5, 7.2.10, and 6.2.19. An additional workaround to mitigate the problem without patching the redis-server executable is to prevent users from executing hyperloglog operations. This can be done using ACL to restrict HLL commands.

Redis 安全漏洞

Redis是美国Redis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，该漏洞源于超日志操作可能导致堆栈或堆越界写入，可能导致远程代码执行。以下版本受到影响：2.8版本至8.0.3版本、7.4.5版本、7.2.10版本和6.2.19之前版本。
