WebKit is basically the browser engine that Apple has been using on various iOS products. WebKit is also part of Safari, and out of those issues 16 were memory corruption issues. These memory corruption errors could end up causing remote code executions through webpages that are malicious.

In terms of the memory corruption issues, one of the bugs was reported by the UK National Cyber Security Center. This was bug labeled CVE-2017-7055. Google Project Zero was also responsible for helping catch some of the bugs that are fixed in iOS 10.3.3. CVE-2017-7060 is also a notable issue that was fixed, which was a Safari Printing bug. This bug would basically give the attacker the ability to freeze up Safari by putting out a bunch of print dialogue buttons.

Another issue was CVE-2017-7063, which was an issue where attackers could end up crashing the Messenger app. Beyond that, other bugs were fixed in the iOS Kernel. Those bugs would have allows for remote execution or give someone access for restricted memory.

Mac Update Released Same Time as iOS 10.3.3

While iOS 10.3.3 might be getting a lot of attention, Apple also released an update for MacOS. There were security fixes put out for Sierra, Yosemite, and El Capitan. These bug fixes also included a lot of the CVE-listed problems, just like in iOS 10.3.3. Most of these vulnerabilities were related to the Intel Graphics Driver. The issues could have allowed someone to execute various arbitrary code from within the Kernel level.

MacoS Kernel and the Wi-Fi protocol both had flaws that were fixed. The Wi-Fi chip could end up being attacked and arbitrary code could be implemented. Just like in iOS 10.3.3, there were a lot of WebKit fixes as well, which impact Safari and the various vulnerabilities from within the browser.

Beyond those two big Apple updates, Apple also released an update for tvOS and WatchOS. The web versions of iTunes and iCloud were also updated, which also included some WebKit security vulnerabilities. Needless to say, Apple has been busy already this week releasing iOS 10.3.3 and other critical system updates for the other Apple products.
