The security issue is caused due to the "crypt()" function only returning the salt when generating salted MD5 hashes and may render e.g. authentication mechanisms relying on the correctness of the "crypt()" function ineffective. The security issue is reported in version 5.3.7. SOLUTION: Fixed in the SVN repository.
