How to fix?

Upgrade freerdp/freerdp to version 2.11.6, 3.5.0 or higher.

Overview

Affected versions of this package are vulnerable to Integer Overflow or Wraparound due to improper handling of certain data structures during the decompression process. An attacker can exploit this vulnerability to cause a denial of service (DoS) condition through crafted packets sent to the affected application. This is only exploitable if the application is configured to use certain graphics extensions (/gfx options) which are enabled by default.

Workaround

This vulnerability can be mitigated by not using /gfx options (e.g., deactivate with /bpp:32 or /rfx).
