Apple released a firmware upgrade for iOS 7.0.6 recently to fix the BUG in SSL connection verification. Open the vulnerability test page with the upgraded ios system https://www.imperialviolet.org: 1266 is no longer open. The page prompts that a secure link cannot be created. Since then, it has been said that Apple has forgotten a major BUG for 18 months and has been successfully repaired. However, the macos bug is not fixed yet. The following prompt is displayed when you open the test page of the above BUG in Safari, but it will not succeed when you open the page using firefox or Chrome.

This vulnerability occurs because it is located in the assumerr and triggers a BUG.

Try to re-compile the program by yourself. If you don't want to missing some header files, Google will be fruitless.
-Update-
The BUG disappears after OSX10.9.2 is updated.
