Description
The pg_dump utility inserted object names literally into comments in the
SQL script it produces. An unprivileged database user could create an
object whose name includes a newline followed by an SQL command. This SQL
command might then be executed by a privileged user during later restore of
the backup dump, allowing privilege escalation. (CVE-2012-0868)
When configured to do SSL certificate verification, PostgreSQL only checked
the first 31 characters of the certificate's Common Name field. Depending
on the configuration, this could allow an attacker to impersonate a server
or a client using a certificate from a trusted Certificate Authority issued
for a different name. (CVE-2012-0867)
CREATE TRIGGER did not do a permissions check on the trigger function to
be called. This could possibly allow an authenticated database user to
call a privileged trigger function on data of their choosing.
