PostgreSQL 9.2.x before 9.2.4 and 9.1.x before 9.1.9 does not properly check REPLICATION privileges, which allows remote authenticated users to bypass intended backup restrictions by calling the (1) pg_start_backup or (2) pg_stop_backup functions.

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.'");
