Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

FreeRDP 3.32.1 之前的版本在 Android 客户端中存在堆越界读取漏洞。恶意 RDP 服务器可通过提供未经验证的 mappedWidth 和 mappedHeight 值，读取表面缓冲区之外的数据。攻击者可发送包含超大尺寸的伪造 RDPGFX_MAP_SURFACE_TO_WINDOW_PDU 数据包，导致 android_UpdateWindowFromSurface 函数从已分配堆内存之外复制数据，从而引发程序崩溃或造成内存信息泄露。

Vulnerability Title
FreeRDP before 3.32.1 Android Client Heap OOB Read via Graphics Pipeline
Source: CVE Program / CVE List V5
Vulnerability Description
FreeRDP before 3.32.1 contains a heap out-of-bounds read vulnerability in the Android client that allows malicious RDP servers to read beyond surface buffers by supplying unvalidated mappedWidth and mappedHeight values. Attackers can send a crafted RDPGFX_MAP_SURFACE_TO_WINDOW_PDU with oversized dimensions, causing android_UpdateWindowFromSurface to copy heap memory beyond the allocation, leading to crashes or memory disclosure.
