Descriptions

FreeRDP is a free implementation of the Remote Desktop Protocol. FreeRDP based clients prior to version 3.5.1 are vulnerable to out-of-bounds read. This occurs when `WCHAR` string is read with twice the size it has and converted to `UTF-8`, `base64` decoded. The string is only used to compare against the redirection server certificate. Version 3.5.1 contains a patch for the issue. No known workarounds are available.

La cadena solo se usa para comparar con el certificado del servidor de redirección. La versión 3.5.1 contiene un parche para el problema. No hay workarounds disponibles.
