Vulnerability Title
Heap-use-after-free in update_pointer_new
Vulnerability Description
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.21.0, `xf_Pointer_New` frees `cursorPixels` on failure, then `pointer_free` calls `xf_Pointer_Free` and frees it again, triggering ASan UAF. A malicious server can trigger a client‑side use after free, causing a crash (DoS) and potential heap corruption with code‑execution risk depending on allocator behavior and surrounding heap layout. Version 3.21.0 contains a patch for the issue.

Vulnerability Title
FreeRDP 资源管理错误漏洞
Vulnerability Description
FreeRDP是FreeRDP团队的一款开源的远程桌面协议（RDP）的实现。 FreeRDP 3.21.0之前版本存在资源管理错误漏洞，该漏洞源于xf_Pointer_New函数在失败时释放cursorPixels，随后pointer_free再次调用xf_Pointer_Free并释放它，可能导致释放后重用，造成崩溃和潜在的堆损坏。
