Affected versions are subject to an IntegerOverflow leading to Out-Of-Bound Write Vulnerability in the gdi_CreateSurface function. This issue affects FreeRDP based clients only. FreeRDP proxies are not affected as image decoding is not done by a proxy. This issue has been addressed in versions 2.11.0 and 3.0.0-beta3. Users are advised to upgrade. There are no known workarounds for this issue.
