PostgreSQL 9.2.x before 9.2.4, 9.1.x before 9.1.9, 9.0.x before 9.0.13, and 8.4.x before 8.4.17, when using OpenSSL, generates insufficiently random numbers, which might allow remote authenticated users to have an unspecified impact via vectors related to the "contrib/pgcrypto functions."
PostgreSQL 8.4.x before 8.4.11, 9.0.x before 9.0.7, and 9.1.x before 9.1.3 truncates the common name to only 32 characters when verifying SSL certificates, which allows remote attackers to spoof connections when the host name is exactly 32 characters.
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.
