CWE ID Description
CWE-416 The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

Executive Summary

This vulnerability exists in FreeRDP, a free implementation of the Remote Desktop Protocol. Before version 3.22.0, the component called video_timer could send client notifications even after the control channel was closed. This caused the software to dereference a callback that had already been freed, leading to a use-after-free condition.

Impact Analysis

The use-after-free vulnerability can lead to undefined behavior such as crashes or potentially allow an attacker to execute arbitrary code. This can compromise the security and stability of systems using vulnerable versions of FreeRDP.
