  A flaw was found in the way the crypt() password hashing function from the
  optional PostgreSQL pgcrypto contrib module performed password
  transformation when used with the DES algorithm. If the password string to
  be hashed contained the 0x80 byte value, the remainder of the string was
  ignored when calculating the hash, significantly reducing the password
  strength. This made brute-force guessing more efficient as the whole
  password was not required to gain access to protected resources.
  (CVE-2012-2143)

  Note: With this update, the rest of the string is properly included in the
  DES hash. Therefore, any previously stored password values that are
  affected by this issue will no longer match. In such cases, it will be
  necessary for those stored password hashes to be updated.

  Upstream acknowledges Rubin Xu and Joseph Bonneau as the original reporters
  of this issue.

  All PostgreSQL users are advised to upgrade to these updated packages,
  which contain a backported patch to correct this issue. If the postgresql
  service is running, it will be automatically restarted after installing
  this update.");
