Descriptions

FreeRDP is a free implementation of the Remote Desktop Protocol. FreeRDP based clients using a version of FreeRDP prior to 3.5.0 or 2.11.6 are vulnerable to integer overflow and out-of-bounds write. Versions 3.5.0 and 2.11.6 patch the issue. As a workaround, do not use `/gfx` options (e.g. deactivate with `/bpp:32` or `/rfx` as it is on by default).

FreeRDP es una implementación gratuita del protocolo de escritorio remoto. Los clientes basados en FreeRDP que utilizan una versión de FreeRDP anterior a la 3.5.0 o 2.11.6 son vulnerables al desbordamiento de enteros y a la escritura fuera de los límites. Las versiones 3.5.0 y 2.11.6 solucionan el problema. Como workaround, no utilice las opciones `/gfx` (por ejemplo, desactívelas con `/bpp:32` o `/rfx`, ya que están activadas de forma predeterminada).

A flaw was found in FreeRDP-based clients. Affected versions of FreeRDP are vulnerable to an integer overflow and out-of-bounds write. This issue occurs when the sum of the `runLengthFactor` and `pixelIndex` values become large enough to overflow the uint32 type and bypass an error check when clearing residual data.
