One More Mac Protocol Handler Exploit
There's another exploitable protocol handler, this time, ssh. Daring Fireball has an excellent summary of what you can do to protect yourself, using RCDefaultApp, and if you went that direction, and were wise enough to recognize ssh might be vulnerable too, you are safe. Paranoid Android attacks the problem from a different direction, and if you use that, you are also safe.
Remember all of the recent exploits are theoretical vulnerabilities and therefore if you have tried out any of the proof of concept code and seen or heard your Mac do anything after clicking on these demonstrations, then you must be imagining things.
"Apple takes security very seriously and works quickly to address potential threats as we learn of them, in this case, before there was any actual risk to our customers,"
Philip Schiller, Apple's senior vice-president of worldwide marketing.
"Users are still as vulnerable as Apple left them last week."
Niels Henrik Rasmussen, Secunia
