Description 小龙 admin 2023-10-17 11:07:14 UTC 
Description:
Spotlight的SambamdssvcRPC服务中发现类型混淆漏洞。解析SpotlightmdssvcRPC数据包时，一种编码数据结构是键值样式字典，其中键是字符串，值可以是mdssvc协议中支持的任何类型。由于dalloc_value_for_key()函数（返回与键关联的对象）的调用者缺乏类型检查，当talloc检测到传入的指针不是有效的talloc指针时，调用者可能会触发talloc_get_size()崩溃。通过在多个客户端连接之间共享RPC工作进程，恶意客户端或攻击者可以在共享RPCmdssvc工作进程中触发进程崩溃，从而影响该工作进程服务的所有其他客户端。
