"PostgreSQL is an advanced object-relational database management system
(DBMS).

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 '$2x$'.

These updated postgresql84 packages upgrade PostgreSQL to version
8.4.9. Refer to the PostgreSQL Release Notes for a full list of
changes :

http://www.postgresql.org/docs/8.4/static/release.html

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."
