Please don't spread misinformation.  If you suspect an issue, *ask a 
question* instead of making seemingly definitive statements.

I'm going to guess (since you didn't specify what your "simple script" 
was) that you ran something like:

$ ruby -ropenssl -e 'puts OpenSSL::OPENSSL_VERSION'
OpenSSL 1.0.1f 6 Jan 2014

OPENSSL_VERSION is a compile-time constant[1]:

> OPENSSL_VERSION
> Version of OpenSSL the ruby OpenSSL extension was built with

IOW, all this tells you is that the (bundled) openssl extension was 
compiled against 1.0.1f, which is true but irrelevant.  What is relevant 
is that it is dynamically linked against openssl:

$ /bin/ldd /usr/lib/ruby/1.9.1/x86_64-cygwin/openssl.so  | grep -v 
$(cygpath -W)
         cygruby191.dll => /usr/bin/cygruby191.dll (0x4738c0000)
         cygcrypt-0.dll => /usr/bin/cygcrypt-0.dll (0x442db0000)
         cygwin1.dll => /usr/bin/cygwin1.dll (0x180040000)
         cygcrypto-1.0.0.dll => /usr/bin/cygcrypto-1.0.0.dll (0x3eed10000)
         cygz.dll => /usr/bin/cygz.dll (0x3c0f60000)
         cygssl-1.0.0.dll => /usr/bin/cygssl-1.0.0.dll (0x3cb7d0000)

And therefore one simply needs to check the currently installed version 
of openssl:

$ cygcheck -c libopenssl100
Cygwin Package Information
Package              Version        Status
libopenssl100        1.0.1g-1       OK

$ openssl version
OpenSSL 1.0.1g 7 Apr 2014

$ ruby -rfiddle -e 'puts 
Fiddle::Function.new(DL.dlopen("cygcrypto-1.0.0.dll")["SSLeay_version"],[Fiddle::TYPE_INT],Fiddle::TYPE_VOIDP).call(0)'
OpenSSL 1.0.1g 7 Apr 2014

If your installation is current, these will be your results, and your 
Cygwin installation is NOT vulnerable to CVE-2014-0160.
