Version: 9.5.24-0ubuntu0.16.04.1 2020-11-17 14:06:22 UTC

  postgresql-9.5 (9.5.24-0ubuntu0.16.04.1) xenial-security; urgency=medium

  * New upstream version.
    + Block DECLARE CURSOR ... WITH HOLD and firing of deferred triggers
      within index expressions and materialized view queries (Noah Misch)

      This is essentially a leak in the security restricted operation sandbox
      mechanism. An attacker having permission to create non-temporary SQL
      objects could parlay this leak to execute arbitrary SQL code as a
      superuser.

      The PostgreSQL Project thanks Etienne Stalmans for reporting this
      problem. (CVE-2020-25695)

    + Fix usage of complex connection-string parameters in pg_dump,
      pg_restore, clusterdb, reindexdb, and vacuumdb (Tom Lane)

      The -d parameter of pg_dump and pg_restore, or the --maintenance-db
      parameter of the other programs mentioned, can be a connection string
      containing multiple connection parameters rather than just a database
      name. In cases where these programs need to initiate additional
      connections, such as parallel processing or processing of multiple
      databases, the connection string was forgotten and just the basic
      connection parameters (database name, host, port, and username) were
      used for the additional connections. This could lead to connection
      failures if the connection string included any other essential
      information, such as non-default SSL or GSS parameters. Worse, the
      connection might succeed but not be encrypted as intended, or be
      vulnerable to man-in-the-middle attacks that the intended connection
      parameters would have prevented. (CVE-2020-25694)

    + When psql's \connect command re-uses connection parameters, ensure that
      all non-overridden parameters from a previous connection string are
      re-used (Tom Lane)

      This avoids cases where reconnection might fail due to omission of
      relevant parameters, such as non-default SSL or GSS options. Worse, the
      reconnection might succeed but not be encrypted as intended, or be
      vulnerable to man-in-the-middle attacks that the intended connection
      parameters would have prevented. This is largely the same problem as
      just cited for pg_dump et al, although psql's behavior is more complex
      since the user may intentionally override some connection parameters.
      (CVE-2020-25694)

    + Prevent psql's \gset command from modifying specially-treated variables
      (Noah Misch)

      \gset without a prefix would overwrite whatever variables the server
      told it to. Thus, a compromised server could set specially-treated
      variables such as PROMPT1, giving the ability to execute arbitrary shell
      code in the user's session.

      The PostgreSQL Project thanks Nick Cleaton for reporting this problem.
      (CVE-2020-25696)

Version: 9.5.23-0ubuntu0.16.04.1 2020-08-25 13:06:20 UTC

  postgresql-9.5 (9.5.23-0ubuntu0.16.04.1) xenial-security; urgency=medium

  * New upstream release (LP: #1892335).
    - Make contrib modules' installation scripts more secure (Tom Lane)

      Attacks similar to those described in CVE-2018-1058 could be carried out
      against an extension installation script, if the attacker can create
      objects in either the extension's target schema or the schema of some
      prerequisite extension. Since extensions often require superuser
      privilege to install, this can open a path to obtaining superuser
      privilege. To mitigate this risk, be more careful about the search_path
      used to run an installation script; disable check_function_bodies within
      the script; and fix catalog-adjustment queries used in some contrib
      modules to ensure they are secure. Also provide documentation to help
      third-party extension authors make their installation scripts secure.
      This is not a complete solution; extensions that depend on other
      extensions can still be at risk if installed carelessly.
      CVE-2020-14350

  postgresql-9.5 (9.5.14-0ubuntu0.16.04) xenial-security; urgency=medium

  * 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)
    - d/libecpg-dev.install: Add new pgtypes header.
    - d/libpgtypes3.symbols: Add new pgtypes symbol.
