Hi,

The following vulnerability was published for freerdp2.

CVE-2024-22211[0]:
| FreeRDP is a set of free and open source remote desktop protocol
| library and clients. In affected versions an integer overflow in
| `freerdp_bitmap_planar_context_reset` leads to heap-buffer overflow.
| This affects FreeRDP based clients. FreeRDP based server
| implementations and proxy are not affected. A malicious server could
| prepare a `RDPGFX_RESET_GRAPHICS_PDU` to allocate too small buffers,
| possibly triggering later out of bound read/write. Data extraction
| over network is not possible, the buffers are used to display an
| image. This issue has been addressed in version 2.11.5 and 3.2.0.
| Users are advised to upgrade. there are no know workarounds for this
| vulnerability.


If you fix the vulnerability please also make sure to include the
