There’s barely any CVEs on that page. It’s likely a security researcher did some fuzzing of the executable and found a few issues at once.
Have you looked at how many vulnerabilities there’s been in things like Windows, MacOS, Chrome, etc?
The point is that there is no software without vulnerabilities.
Definitely true, but that conflicts with this:
Coincidentally, security was one of the reasons to uninstall 7-Zip.
If you uninstalled software because of security, you wouldn’t have any software left :)
Also true. I was probably too impatient when I bought a WinRAR license over night. But now I have it and I use it. :-)
