WinRAR archiver has has serious security bug for 10+ years but it was only recently notified.
Update it immediately to continue safe use.
500 million people prefer to use WinRAR over opensource alternatives, telling maybe something about the quality of opensource.
There is now 100 security attacks which utilise WinRAR to gain access to your files.
>ALL OF THEM require some version of Microsoft Windows while Linux is invulnerable to this bug even if a Linux user uses WinRAR, which is possible to do
Nearly all archiver formats have some patch traversal mechanism that can be exploited and extract file outside it's archive's root directory. I really wish devs were not such retards. It's not a crime to have something like that in specs, but then implementing a safe mode and making it default is essential and verifying safe archive should be trivial.
