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.

在 FreeRDP 3.32.0 之前的版本中， 函数存在一个堆缓冲区溢出漏洞。本地攻击者可以通过提供一个精心构造的 v3 持久缓存文件来破坏内存。攻击者可以设置较大的宽度和高度值，导致 中的大小计算发生回绕（wrap around），从而使 向一个尺寸过小的缓冲区写入数据时发生溢出，并可能实现代码执行。

Vulnerability Title
FreeRDP before 3.32.0 Heap Buffer Overflow via persistent_cache_read_entry_v3
Source: CVE Program / CVE List V5
Vulnerability Description
FreeRDP before 3.32.0 contains a heap buffer overflow vulnerability in persistent_cache_read_entry_v3 that allows local attackers to corrupt memory by supplying a crafted v3 persistent cache file. Attackers can set large width and height values that wrap the size calculation in persist_cache_get_data, causing fread to overflow an undersized buffer and potentially execute code.
