Now, however, the scope of that security flaw has widened. It seems that in conjunction with the flaw, another flaw in a separate browser, IE, can also be exploited. Together they spell trouble, this time in the form of a system compromise. The IE flaw allows code to be executed on the machine, which in turn most likely leads to a machine taken over.
The flaw doesn't take a lot of effort, only requiring someone visit a maliciously crafted webpage. Given that even high profile sites run by industry “leaders” can be hacked, accidentally visiting a nasty page isn't that rare. There is currently no fix for either IE or Safari. This bug is in a small group of bugs that have come to light in the past few years that require certain combinations of software to be installed.
