FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Affected versions of the 3.x beta branch are subject to a Use-After-Free issue in the avc420_ensure_buffer and avc444_ensure_buffer functions. If the value of piDstSize[x] is 0, ppYUVDstData[x] will be freed. However, in this case ppYUVDstData[x] will not have been updated which leads to a Use-After-Free vulnerability. This issue has been addressed in version 3.0.0-beta3. Users of the 3.x beta releases are advised to upgrade. There are no known workarounds for this vulnerability.
