Any os utilizing software with exploits will be vunerable. Updates however have been issued when they are available and are installed automatically by default in lxle. Running Linux is probably less likely to be exploited by these bugs particularly if they then rely on different technologies that are only window or mac specific. Also there is a certain level of security through obscurity in otherwords linux is a tear drop in a bucket thats dumped in the ocean. Not usually a big target for cybercriminals.
