Postgresql was updated to version 9.0.13 : * CVE-2013-1899: Fix insecure parsing of server command-line switches. A connection request containing a database name that begins with "-" could be crafted to damage or destroy files within the server"s data directory, even if the request is eventually rejected. * CVE-2013-1900: Reset OpenSSL randomness state in each postmaster child process. This avoids a scenario wherein random numbers generated by "contrib/pgcrypto" functions might be relatively easy for another database user to guess. The risk is only significant when the postmaster is configured with ssl = on but most connections don"t use SSL encryption. * CVE-2013-1901: Make REPLICATION privilege checks test current user not authenticated user. An unprivileged database user could exploit this mistake to call pg_start_backup or pg_stop_backup, thus possibly interfering with creation of routine backups
