Descriptions
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.
FreeRDP es una implementación gratuita del Protocolo de escritorio remoto (RDP), publicada bajo la licencia Apache. Las versiones afectadas están sujetas a una validación de compensación no válida que conduce a una escritura fuera de límites. Esto se puede activar cuando los valores `rect->left` y `rect->top` son exactamente iguales a `surface->width` y `surface->height`. p.ej. `rect->izquierda` == `superficie->ancho` && `rect->top` == `superficie->alto`. En la práctica, esto debería provocar un bloqueo. Este problema se solucionó en las versiones 2.11.0 y 3.0.0-beta3. Se recomienda a los usuarios que actualicen. No se conocen soluciones para esta vulnerabilidad.
