The remote Amazon Linux AMI host is missing a security update.
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 '$2x$'.
