Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 MPack 1.1.1 的 MPack Node API 中，32 位平台上存在一个整数溢出漏洞。当解析包含过多元素数量的特制 MessagePack array32 或 map32 对象时，mpack_tree_parse_children() 函数中的页面分配大小计算可能导致 size_t 类型溢出，从而产生过小的内存分配。随后，解析过程会在已分配的堆缓冲区之外写入 mpack_node_data_t 记录，导致堆缓冲区溢出、内存损坏以及拒绝服务（DoS）。

Vulnerability Description
An integer overflow vulnerability exists in the MPack Node API in MPack 1.1.1 on 32-bit platforms. When parsing a specially crafted MessagePack array32 or map32 object with an excessively large element count, the page allocation size calculation in mpack_tree_parse_children() can overflow size_t and produce an undersized allocation. Subsequent parsing writes mpack_node_data_t records beyond the allocated heap buffer, resulting in heap-buffer-overflow, memory corruption, and denial of service.
