Description Jan Lieskovsky 2012-04-27 07:02:13 EDT
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.

Statement:

This issue did not affect the version of php as shipped with Red Hat Enterprise Linux 5 as it did not include FreeSec's libcrypt cryptographic algorithms implementation yet. This issue was addressed in php53 package for Red Hat Enterprise Linux 5 via RHSA-2012:1047 and in php package for Red Hat Enterprise Linux 6 via RHSA-2012:1046.
