CVE-2012-2143

First published: Fri Apr 27 2012(Updated: )

A security flaw was found in the way DES and extended DES based crypt() password encryption function performed encryption of certain keys, when the key to be encrypted was provided in the Unicode encoding (certain keys were truncated before being DES digested). When the resulting ciphertext for such a previously shortened key was used as a pattern in a password protected resource, intended to be matched against subsequently encrypted value of the password field, retrieved from the user authentication dialog, it could lead to authentication bypass.
