Apple has issued emergency security updates for OS X El Capitan and OS X Yosemite to fix some major problems that had come to light codenamed Trident.
The company released the fixes a week after security researchers found flaws in iOS, suggesting that they could be linked. Apple issued a rushed fix for these flaws too, given their severity.
Apple has only basic information about the fixes, but there is enough in there to suggest that they could give hackers arbitrary execution powers if exploited.
"Impact: an application may be able to disclose kernel memory," stated one flaw. The other said: "Impact: an application may be able to execute arbitrary code with kernel privileges."
The advice from the industry is to install and update as soon as possible.
"September brings us a new update which appears to be a late response to the iOS zero-day vulnerabilities patched last week in iOS 9.3.5," said Stephen Brown, director of product management at LANDESK.
"Because of the nature of the exploits in these vulnerabilities, and the small size of the update, these updates should be treated as critical and applied quickly."
Two security research firms have been credited with bringing the problems to Apple's attention, Citizen Lab and Lookout. Citizen Lab applauded Apple for its swift reaction and repair work.
"We encourage all Apple users to install the update as soon as possible," the firm added.
