| Doc Text: |
A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. A malicious Remote Desktop Protocol (RDP) server can exploit a heap buffer overflow vulnerability during Opus audio decoding. This occurs when the server negotiates Opus audio with a vulnerable client, causing the client to write data beyond an allocated memory buffer. This can lead to client crashes, memory corruption, and potentially allow the malicious server to execute arbitrary code on the client system.
