Exploitability
| 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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer. |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability exists in FreeRDP, a free implementation of the Remote Desktop Protocol. Before version 3.22.0, there was an issue with AUDIN format renegotiation where the active format list was freed while the capture thread was still using it. This caused a use-after-free condition in the function audio_format_compatible.
A use-after-free vulnerability occurs when a program continues to use memory after it has been freed, which can lead to crashes or potentially allow an attacker to execute arbitrary code.
This issue was fixed in FreeRDP version 3.22.0.
How can this vulnerability impact me? :
The use-after-free vulnerability in FreeRDP can lead to serious security impacts such as application crashes or potentially arbitrary code execution by an attacker.
Since FreeRDP is used for remote desktop connections, exploitation of this vulnerability could allow an attacker to compromise the system running the vulnerable version, leading to unauthorized access or control.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
