  A signedness issue was found in the way the crypt() function in the
  PostgreSQL pgcrypto module handled 8-bit characters in passwords when using
  Blowfish hashing. Up to three characters immediately preceding a non-ASCII
  character (one with the high bit set) had no effect on the hash result,
  thus shortening the effective password length. This made brute-force
  guessing more efficient as several different passwords were hashed to the
  same value. (CVE-2011-2483)

  Note: Due to the CVE-2011-2483 fix, after installing this update some users
  may not be able to log in to applications that store user passwords, hashed
  with Blowfish using the PostgreSQL crypt() function, in a back-end
  PostgreSQL database. Unsafe processing can be re-enabled for specific
  passwords (allowing affected users to log in) by changing their hash prefix
  to '$2x$'.

  For Red Hat Enterprise Linux 6, the updated postgresql packages upgrade
  PostgreSQL to version 8.4.9. Refer to the linked PostgreSQL Release Notes for a
  full list of changes.

  For Red Hat Enterprise Linux 4 and 5, the updated postgresql packages
  contain a backported patch.

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