MAC OS X Security
The bug should’ve been squashed in the latest update of OS X 10.10.3, but researchers say it persists. Every Mac is at risk from this “backdoor” bug.
A bug that Apple said it fixed in the latest release of its OS X desktop operating system continues to plague every Mac owner, after a researcher found a way to exploit the flaw again.
Dubbed “rootpipe,” researchers claimed the vulnerability allows hackers or malicious actors to escalate a user’s privileges, making it easier to spread system-wide malware or take over an entire machine.
Apple indicated that the bug would only be fixed in the latest version of its software, OS X Yosemite, effectively forcing every older operating system user to upgrade in order to be patched. Video About MAC OS X Security
But, one researcher took a second attempt at exploiting the vulnerability on a patched machine, and succeeded.
Patrick Wardle said he was on a flight home when he found a “novel, yet trivial way” for any user to exploit the vulnerability for a second time — even on a patched machine — allowing the user to become the highest user privilege level, known as “root.”
