Recently Google discovered the "glibc getaddrinfo" vulnerability (CVE-2015-7547).
Does this vulnerability affect Windows systems at all? I think it might because I'm not sure that glibc is a Linux-only piece of software. It might be able to be part of a Windows software or it might run emulated on Windows (Cygwin?!). I have searched for "glibc windows" but the search results are inconclusive to me.
Is this concern valid at all?
