Description

FreeRDP is a free implementation of the Remote Desktop Protocol. FreeRDP based clients using a version of FreeRDP prior to 3.5.0 or 2.11.6 are vulnerable to integer overflow and out-of-bounds write. Versions 3.5.0 and 2.11.6 patch the issue. As a workaround, do not use `/gfx` options (e.g. deactivate with `/bpp:32` or `/rfx` as it is on by default).

Affected products

• 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.
