Descriptions

The SwiftKey language-pack update implementation on Samsung Galaxy S4, S4 Mini, S5, and S6 devices relies on an HTTP connection to the skslm.swiftkey.net server, which allows man-in-the-middle attackers to write to language-pack files by modifying an HTTP response. NOTE: CVE-2015-4640 exploitation can be combined with CVE-2015-4641 exploitation for man-in-the-middle code execution.

La implementación de la actualización del paquete de lenguas SwiftKey en los dispositivos Samsung Galaxy S4, S4 Mini, S5, y S6 depende de una conexión HTTP al servidor skslm.swiftkey.net, lo que permite a atacantes man-in-the-middle escribir en ficheros del paquete de lenguas mediante la modificación de una respuesta HTTP. NOTA: La explotación de CVE-2015-4640 puede combinarse con la explotación de CVE-2015-4641 para la ejecución de código man-in-the-middle.
