Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
在 Eclipse Vert.x 的以下版本中：[4.0.0, 4.5.34]、[5.0.0, 5.0.12]、[5.1.0, 5.1.9] 或 [5.2.0, 5.2.0]，Vert.x Redis 客户端的 RESP 解析器会根据服务器声明的长度预分配数组，而未对其施加上限约束。恶意或已被攻陷的 Redis 服务器，或处于中间人位置的攻击者，可以发送一个精心构造的 RESP 响应，声明一个极其庞大的数组、推送列表或属性长度，从而导致客户端尝试进行巨大的堆内存分配。由此引发的 OutOfMemoryError（内

Vulnerability Description
In Eclipse Vert.x versions [4.0.0, 4.5.34] or [5.0.0,5.0.12] or [5.1.0,5.1.9] or [5.2.0, 5.2.0], the Vert.x Redis client RESP parser pre-allocates arrays to a length declared by the server without enforcing an upper bound. A malicious or compromised Redis server, or an attacker in a man-in-the-middle position, can send a crafted RESP response declaring an extremely large array, push, or attribute length, causing the client to attempt a massive heap allocation. The resulting OutOfMemoryError crashes the Vert.x event loop thread, denying service to all connections and verticles sharing that loop.
The impacted component is io.vertx:vertx-mysql-client.
