When Apple updates iOS, macOS, and the rest of its operating systems, it typically includes new features, performance, and security improvements, covering any vulnerabilities discovered. It is the eternal race between authors and developers of malicious code: all loopholes that could allow the system to be abused to the detriment of users must be closed.
We know there are quite a few updates from Apple, we just have to look at all the version numbers that have come out over the years. But Who counts all the vulnerabilities that have occurred? Well, there is a website that does just that.
The Wikipedia of vulnerabilities
The website in question is called CVE Details and consists of an extensive database of all security gaps and vulnerabilities that have impacted the devices and systems most used by the general public. Apple has a dedicated section where you can see a summary of all vulnerabilities by year on the cover.

On the same cover we see strange dates such as that 2015 was the year when there were more security problems in Apple systems and that the main problem was that someone could exploit a security hole to perform malicious code inside the system.
For example, if we go to the iOS vulnerabilities section, we will see a list where luckily they are all fixed and have a Danger Score of 0.0 (At a value of 10, the danger is at its maximum). Each vulnerability has its own tab: Here is an example of the most recent vulnerability at the time of this writing, which is a bug of this type outside the limits allowed you to run code in the system kernel with administrator privileges. As mentioned earlier, Apple has already covered the vulnerability.
This site can be useful for developers and security professionals who want to know about bugs they’ve discovered and want to check if Apple has been able to fix them. And for curious or interested people like us, it can be a perfect reference site.
