FreeRDP is a free implementation of the Remote Desktop Protocol (RDP),
released under the Apache license. 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.
