A remote-code execution vulnerability in Windows Defender – a flaw that can be exploited by malicious .rar files to run malware on PCs – has been traced back to an open-source archiving tool Microsoft adopted for its own use.
[...] Apparently, Microsoft forked that version of unrar and incorporated the component into its operating system's antivirus engine. That forked code was then modified so that all signed integer variables were converted to unsigned variables, causing knock-on problems with mathematical comparisons. This in turn left the software vulnerable to memory corruption errors, which can crash the antivirus package or allow malicious code to potentially execute.

Nice try, but Bzip2 is BSD-licensed. Obviously RMS would advocate the use of gzip, which is GPL...and, y'know, part of that whole GNU project that is sort of his life's work.
Hand in your nerd card on the way out.
