FreeRDP 版本在 3.13.0 至 3.32.0（不含 3.32.0）之间存在资源泄露漏洞，位于 drive_process_irp_create 函数中。该函数在应用分配大小之前，会将已打开的本地文件注册到磁盘共享字典中；若后续分配大小操作失败，则不会将该文件对象从字典中移除。当启用了磁盘重定向功能的客户端连接到一个恶意 RDP 服务器时，该服务器可发送 IRP_MJ_CREATE 请求，并将 AllocationSize 设置为 UINT64_MAX，从而迫使文件定位（seek）操作失败，导致文件对象及操

Vulnerability Title
FreeRDP 3.13.0 before 3.32.0 Resource Leak via Drive Redirection IRP_MJ_CREATE
Source: CVE Program / CVE List V5
Vulnerability Description
FreeRDP versions 3.13.0 before 3.32.0 contain a resource retention flaw in drive_process_irp_create, which registers an opened local file in the drive dictionary before applying the allocation size and does not remove it when that operation fails. A malicious RDP server connected to a client with drive redirection enabled can send IRP_MJ_CREATE with AllocationSize set to UINT64_MAX, forcing the seek to fail and leaking the file object and operating-system handle until drive teardown.
