Yet it doesn't have an auto update or an update notifier. And this is why it's bad and dangerous when applications can't auto update.

Thanks for the heads-up! I doubt I'd have noticed a thing like this otherwise.

@BlueRay: Please keep in mind even update servers may infect themselfes. This has been done in the past multiple times. The last time I know was some kind of banking software which downloaded an infected update (crypto trojan) from its compromised update servers. Because autoupdates were ON by default, half its clients were infected.

On the one hand may be wise to let programs autoupdate themselfes if you trust them >>and the whole chain<<.
On the other hand it may be even better to disable autoupdates and do the patching the manual way on critical infrastructure. Remember the time when Windows 10 updates broke some computers? (Isn't it still a thing today?)
My grandma would be better off with autoupdates which >>I<< enable, for the most important programs.
Personally I feel safer with a weekly "patchday", where I download (or check for) program updates. A big PRO is you do not have to have dozens of programs running in the background, checking for updates every few minutes / hours. Saves bandwidth, ressources and therefore energy (a small bit). "Green IT by disabling autoupdaters." ;-)

I used 7-zip for many many years and still use it today. It offers all the formats you want your archive program to support. RAR, ZIP, 7Z, WIM, ISO and a lot more is supported. That is what I care of the most, after the fact it's free without any hidden fees and does not come with any spyware, adware, other crap bundled. ("Hi FlashPlayer!").

I do not care about the security issue found here. Honestly: Every program has these. But after escalating the issue to the publisher you see if you may trust them in the future. If a bug does not get patched, this is far worse from my point of view than a program who has thousands of bugs but they get fixed in week 1. The publishers of 7-zip did their job right and fixed the bug. They communicated this to the public the right way (AFTER the patch is available but still in a reasonable "short" period of time), so no bad feelings about this.

IT department uses 7zip, no update queued as of right now.
IT department releases win10 on newer (Dell) laptops, and I'm not sure they know what to deactivate and what not.

As you might think, my trust in my company's IT department is not that big

@386SX I understand that but a notification prompting user to go to the website and download the new version is the bare minimum for security. It is the most popular zip tool yet it expects users to read tech blogs to find out their version is not secure. This is bad.

Thanks, downloaded & installed!

I agree with you with notifications, for any standard user this would be optimal and saves me a lot of work at friends or family.

THX for letting us know, 7z is must for anyone.

Ohh

H.H. please use this version to bench CPU, Ígor Pávlov is always working to improve 7-zip

I'm glad it was dealt with as quickly as they did.

One day I discovered Chocolatey:
https://chocolatey.org/

Since that day, updates on free software are no longer a concern.

p.s. - 7-Zip is already updated in the repository - It says version 18.5, and not 18.05 (but it's same thing)

Another reason to upgrade:

You know its not remote code execution if you have to download a file first and open it locally. Whats with the security people these days.

Obviously something like 7-Zip which is not a persistent service of any kind will likely never be affected by Remote Code Execution, since remote hackers cannot interact with it whatsoever - unless you have a web-service that somehow interacts with 7-Zip (to unpack uploaded files, for example), but thats reaching.

I use PatchMyPC. Real handy and easy.

Nice tool, but that program is a little toy compared to Choco:

"There are 5762 community maintained packages" (currently)

This one is the Windows equivalent of Ubuntu package manager... it can install, uninstall, update software, look for new software in various categories, etc. I a completely different class than that little tool.

Oh, and there is a GUI as well (which I'm using), so I don't mess around with commandline:
