Serious exploit discovered in OS X Yosemite

It looks like a serious security flaw was discovered in many versions of Apple’s OS X, including the recently launched Yosemite. There’s isn’t much info on how it works but Apple is reportedly trying to fix it already.

The news came via a Swedish hacker, who found the so called “rootpipe” vulnerability in older versions of Apple’s OS. He then discovered that with some small modifications the same exploit could be used on Yosemite.

Rootpipe allows a malicious attacker to gain root privileges from an admin account and run sudo commands, bypassing the usual security employed by the OS. Kvarnhammar, the hacker who discovered the flaw, did not want to disclose further info on the flaw, while we wait for Apple to patch it – a timeframe tentatively set for January 2015.

Until then the usual safety recommendations apply, such as not using admin accounts for day to day operations, and turning on hard-drive encryption if you handle sensitive data.
