The issue is both present on the PowerPC versions of the modem and the ARM versions.\n\nA stack buffer buffer overflow in the swdownload binary allows attackers to execute arbitrary code. The parse_INFO function uses an unrestricted `sscanf` to read a string of an incoming network packet into a statically sized buffer.",
