FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, the function Stream_EnsureCapacity can create an endless blocking loop. This may affect all client and server implementations using FreeRDP. For practical exploitation this will only work on 32bit systems where the available physical memory is &gt;= SIZE_MAX. Version 3.23.0 contains a patch. No known workarounds are available.
