Apple took advantage of the recent release of OS X 10.10.5 to address critical security vulnerabilities found earlier, in addition to offering other pending improvements to Yosemite users. But it only took a few days for a new bug to be discovered, capable of severely compromising any Mac with the latest updates installed.
This time, two memory corruption bugs can be used to compromise the kernel of the operating system through installation of malicious software. The discovery was published on GitHub by the young man Luca Todesco, an Italian only 18 years old.
The initiative, however, preceded an opportunity to inform Apple about the existence of the flaws, which according to PCWorld generated some controversy. Although the company has a history of not reacting quickly when correcting and delivering security updates, responses to the latest bugs found happened at a better pace.
For test users of OS X El Capitan, the vulnerabilities found by Todesco were not detected in the latest version released by Apple. Therefore, it is estimated that the effort required to update Yosemite and previous versions will be minimal.
