  * New upstream version 17.6.

    + Tighten security checks in planner estimation functions (Dean Rasheed)

      The fix for CVE-2017-7484, plus followup fixes, intended to prevent
      leaky functions from being applied to statistics data for columns that
      the calling user does not have permission to read.  Two gaps in that
      protection have been found.  One gap applies to partitioning and
      inheritance hierarchies where RLS policies on the tables should restrict
      access to statistics data, but did not.

      The other gap applies to cases where the query accesses a table via a
      view, and the view owner has permissions to read the underlying table
      but the calling user does not have permissions on the view. The view
      owner's permissions satisfied the security checks, and the leaky
      function would get applied to the underlying table's statistics before
      we check the calling user's permissions on the view.  This has been
      fixed by making security checks on views occur at the start of planning.
      That might cause permissions failures to occur earlier than before.

      The PostgreSQL Project thanks Dean Rasheed for reporting this problem.

    + Prevent pg_dump scripts from being used to attack the user running the
      restore (Nathan Bossart)

      Since dump/restore operations typically involve running SQL commands as
      superuser, the target database installation must trust the source
      server.  However, it does not follow that the operating system user who
      executes psql to perform the restore should have to trust the source
      server.  The risk here is that an attacker who has gained
      superuser-level control over the source server might be able to cause it
      to emit text that would be interpreted as psql meta-commands. That would
      provide shell-level access to the restoring user's own account,
      independently of access to the target database.

      To provide a positive guarantee that this can't happen, extend psql with
      a restrict command that prevents execution of further meta-commands,
      and teach pg_dump to issue that before any data coming from the source
      server.

      The PostgreSQL Project thanks Martin Rakhmanov, Matthieu Denais, and
      RyotaK for reporting this problem. (CVE-2025-8714)

    + Convert newlines to spaces in names included in comments in pg_dump
      output (Noah Misch)

      Object names containing newlines offered the ability to inject arbitrary
      SQL commands into the output script.  (Without the preceding fix,
      injection of psql meta-commands would also be possible this way.)
      CVE-2012-0868 fixed this class of problem at the time, but later work
      reintroduced several cases.

      The PostgreSQL Project thanks Noah Misch for reporting this problem.

  * New upstream version 17.5.

    + Avoid one-byte buffer overread when examining invalidly-encoded strings
      that are claimed to be in GB18030 encoding (Noah Misch, Andres Freund)

      While unlikely, a SIGSEGV crash could occur if an incomplete multibyte
      character appeared at the end of memory.  This was possible both in the
      server and in libpq-using applications. (CVE-2025-4207)

    + Improve behavior of libpq's quoting functions (Andres Freund, Tom Lane)

      The changes made for CVE-2025-1094 had one serious oversight:
      PQescapeLiteral() and PQescapeIdentifier() failed to honor their string
      length parameter, instead always reading to the input string's trailing
      null.  This resulted in including unwanted text in the output, if the
      caller intended to truncate the string via the length parameter.  With
      very bad luck it could cause a crash due to reading off the end of
      memory.

      In addition, modify all these quoting functions so that when invalid
      encoding is detected, an invalid sequence is substituted for just the
      first byte of the presumed character, not all of it.  This reduces the
      risk of problems if a calling application performs additional processing
      on the quoted string.

postgresql-17 (17.3-1) unstable; urgency=medium

  * New upstream version 17.3.

    + Harden PQescapeString and allied functions against invalidly-encoded
      input strings (Andres Freund, Noah Misch)

      Data-quoting functions supplied by libpq now fully check the encoding
      validity of their input.  If invalid characters are detected, they
      report an error if possible.  For the ones that lack an error return
      convention, the output string is adjusted to ensure that the server will
      report invalid encoding and no intervening processing will be fooled by
      bytes that might happen to match single quote, backslash, etc.

      The purpose of this change is to guard against SQL-injection attacks
      that are possible if one of these functions is used to quote crafted
      input.  There is no hazard when the resulting string is sent directly to
      a PostgreSQL server (which would check its encoding anyway), but there
      is a risk when it is passed through psql or other client-side code.
      Historically such code has not carefully vetted encoding, and in many
      cases it's not clear what it should do if it did detect such a problem.

      This fix is effective only if the data-quoting function, the server, and
      any intermediate processing agree on the character encoding that's being
      used.  Applications that insert untrusted input into SQL commands should
      take special care to ensure that that's true.

      Applications and drivers that quote untrusted input without using these
      libpq functions may be at risk of similar problems.  They should first
      confirm the data is valid in the encoding expected by the server.

      The PostgreSQL Project thanks Stephen Fewer for reporting this problem.

postgresql-17 (17.2-1) unstable; urgency=medium

  * New upstream version 17.2.

    + Repair ABI break for extensions that work with struct ResultRelInfo

      Last week's minor releases unintentionally broke binary compatibility
      with timescaledb and several other extensions.  Restore the affected
      structure to its previous size, so that such extensions need not be
      rebuilt.

    + Restore functionality of ALTER {ROLE|DATABASE} SET role

      The fix for CVE-2024-10978 accidentally caused settings for role to not
      be applied if they come from non-interactive sources, including previous
      ALTER {ROLE|DATABASE} commands and the PGOPTIONS environment variable.

postgresql-17 (17.1-1) unstable; urgency=medium

  * New upstream version 17.1.

    + Ensure cached plans are marked as dependent on the calling role when RLS
      applies to a non-top-level table reference (Nathan Bossart)

      If a CTE, subquery, sublink, security invoker view, or coercion
      projection in a query references a table with row-level security
      policies, we neglected to mark the resulting plan as potentially
      dependent on which role is executing it.  This could lead to later query
      executions in the same session using the wrong plan, and then returning
      or hiding rows that should have been hidden or returned instead.

      The PostgreSQL Project thanks Wolfgang Walther for reporting this
      problem. (CVE-2024-10976)

    + Make libpq discard error messages received during SSL or GSS protocol
      negotiation (Jacob Champion)

      An error message received before encryption negotiation is completed
      might have been injected by a man-in-the-middle, rather than being real
      server output.  Reporting it opens the door to various security hazards;
      for example, the message might spoof a query result that a careless user
      could mistake for correct output.  The best answer seems to be to
      discard such data and rely only on libpq's own report of the connection
      failure.

      The PostgreSQL Project thanks Jacob Champion for reporting this problem.
      (CVE-2024-10977)

    + Fix unintended interactions between SET SESSION AUTHORIZATION and SET
      ROLE (Tom Lane)

      The SQL standard mandates that SET SESSION AUTHORIZATION have a
      side-effect of doing SET ROLE NONE.  Our implementation of that was
      flawed, creating more interaction between the two settings than
      intended. Notably, rolling back a transaction that had done SET SESSION
      AUTHORIZATION would revert ROLE to NONE even if that had not been the
      previous state, so that the effective user ID might now be different
      from what it had been before the transaction.  Transiently setting
      session_authorization in a function SET clause had a similar effect. A
      related bug was that if a parallel worker inspected
      current_setting('role'), it saw none even when it should see something
      else.

      The PostgreSQL Project thanks Tom Lane for reporting this problem.
      (CVE-2024-10978)

    + Prevent trusted PL/Perl code from changing environment variables
      (Andrew Dunstan, Noah Misch)

      The ability to manipulate process environment variables such as PATH
      gives an attacker opportunities to execute arbitrary code.  Therefore,
      trusted PLs must not offer the ability to do that.  To fix plperl,
      replace %ENV with a tied hash that rejects any modification attempt with
      a warning. Untrusted plperlu retains the ability to change the
      environment.

      The PostgreSQL Project thanks Coby Abrams for reporting this problem.
