Description
FreeRDP is a free implementation of the Remote Desktop Protocol. FreeRDP based based clients using `/bpp:32` legacy `GDI` drawing path with a version of FreeRDP prior to 3.5.0 or 2.11.6 are vulnerable to out-of-bounds read. Versions 3.5.0 and 2.11.6 patch the issue. As a workaround, use modern drawing paths (e.g. `/rfx` or `/gfx` options). The workaround requires server side support.

- FreeRDP: before 2.11.6; from 3.0.0 before 3.5.0 — fixed in 2.11.6, 3.5.0
How to fix
Upgrade to a fixed version: FreeRDP 2.11.6, 3.5.0. Check the vendor advisory for mitigations.
