FreeRDP is a free implementation of the Remote Desktop Protocol (RDP),
released under the Apache license. Affected versions are subject to an
invalid offset validation leading to Out Of Bound Write. This can be
triggered when the values rect->left and rect->top are exactly equal to
surface->width and surface->height. eg. rect->left ==
surface->width && rect->top == surface->height. In practice this
should cause a crash. 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 vulnerability.
