Apple quashes 3 zero-days with emergency Mac update
Apple yesterday issued an emergency security update for the Mac, patching the same trio of vulnerabilities the company fixed last week on the iPhone.
According to one of the groups that first revealed the flaws, the vulnerabilities could have been “weaponized” for use against OS X, the Mac’s operating system.
The out-of-band update was aimed at OS X El Capitan (aka 10.11) and Yosemite (10.10), the 2015 and 2014 editions, respectively. Older versions, including 2014’s OS X Mavericks, went unpatched: Apple is nearing the release of its annual Mac operating system upgrade and thus the end of support for the edition of three years ago.
Like the urgent update Apple released last week for the iPhone — iOS 9.3.5 — the Mac patches quash three bugs, two in the operating system’s kernel and the third in the Safari browser.
