* New upstream release (LP: #1786938)
- Fix failure to reset libpq's state fully between connection attempts
.
An unprivileged user of dblink or postgres_fdw could bypass the checks
intended to prevent use of server-side credentials, such as a ~/.pgpass
file owned by the operating-system user running the server. Servers
allowing peer authentication on local connections are particularly
vulnerable. Other attacks such as SQL injection into a postgres_fdw
session are also possible. Attacking postgres_fdw in this way requires
the ability to create a foreign server object with selected connection
parameters, but any user with access to dblink could exploit the
problem. In general, an attacker with the ability to select the
connection parameters for a libpq-using application could cause
mischief, though other plausible attack scenarios are harder to think
of. Our thanks to Andrew Krasichkov for reporting this issue.
(CVE-2018-10915)
- Fix INSERT ... ON CONFLICT UPDATE through a view that isn't just SELECT
FROM ...
.
Erroneous expansion of an updatable view could lead to crashes or
attribute ... has the wrong type errors, if the view's SELECT list
doesn't match one-to-one with the underlying table's columns.
Furthermore, this bug could be leveraged to allow updates of columns
that an attacking user lacks UPDATE privilege for, if that user has
INSERT and UPDATE privileges for some other column(s) of the table. Any
user could also use it for disclosure of server memory.
(CVE-2018-10925)
