Ryan Petrich well-known Cydia app developer, has released a patch that fixes the vulnerability SSL on iOS 6.x and 7.x.
Apple released iOS 7.0.6 recently to fix the “bug.” The patch for this reason is essentially useless, since there is no reason not to apply the official one information by Apple.
The package is called "SSLPatch" and is available at a private Petrich repo at http://rpetri.ch/repo/.
Once you've installed the patch you can go to http://www.gotofail.com to make sure your device is secure.
