Security researcher Holger Fuhrmannek reported that when the Updater
is opened directly using the callback application path parameter, a copy of a user
specified file is made as a callback file. If the target of this file is made with a
locked hardlink, an arbitrary local file can be replaced on the system even if there is no
privileged write access to the targeted file. If this targeted file is run by other
processes with privileges, this could allow for arbitrary code execution by a malicious
user with local system access. This is not exploitable by web content.");
