Fix failure to reset <application>libpq</application>'s state fully
between connection attempts (Tom Lane)
</para>
<para>
An unprivileged user of <filename>dblink</filename>
or <filename>postgres_fdw</filename> could bypass the checks intended
to prevent use of server-side credentials, such as
a <filename>~/.pgpass</filename> 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 <filename>postgres_fdw</filename> session
are also possible.
Attacking <filename>postgres_fdw</filename> in this way requires the
ability to create a foreign server object with selected connection
parameters, but any user with access to <filename>dblink</filename>
could exploit the problem.
In general, an attacker with the ability to select the connection
parameters for a <application>libpq</application>-using application
could cause mischief, though other plausible attack scenarios are
harder to think of.
Our thanks to Andrew Krasichkov for reporting this issue.
