Descriptions

In FreeRDP before version 2.1.2, there is a global OOB read in update_read_cache_bitmap_v3_order. As a workaround, one can disable bitmap cache with -bitmap-cache (default). This is fixed in version 2.1.2.

En FreeRDP versiones anteriores a 2.1.2, se presenta una lectura OOB global en update_read_cache_bitmap_v3_order. Como solución alternativa, se puede deshabilitar la memoria caché de mapa de bits con -bitmap-cache (predeterminado). Esto es corregido en la versión 2.1.2
