postgresql-17 (17.10-1) unstable; urgency=medium

  * New upstream version 17.10.

    + Prevent unbounded recursion while processing startup packets
      (Michael Paquier)

      A malicious client could crash the connected backend by alternating
      rejected SSL and GSS encryption requests indefinitely.

      The PostgreSQL Project thanks Calif.io (in collaboration with Claude and
      Anthropic Research) for reporting this problem. (CVE-2026-6479)

    + Fix assorted integer overflows in memory-allocation calculations
      (Tom Lane, Nathan Bossart, Heikki Linnakangas)

      Various places were incautious about the possibility of integer overflow
      in calculations of how much memory to allocate.  Overflow would lead to
      allocating a too-small buffer which the caller would then write past the
      end of.  This would at least trigger server crashes, and probably could
      be exploited for arbitrary code execution.  In many but by no means all
      cases, the hazard exists only in 32-bit builds.

      The PostgreSQL Project thanks Xint Code, Bruce Dang, Sven Klemm, and
      Pavel Kohout for reporting these problems. (CVE-2026-6473)

    + Properly quote subscription names in pg_createsubscriber
      (Nathan Bossart)

      The given subscription name was inserted into SQL commands without
      quoting, so that SQL injection could be achieved in the (perhaps
      unlikely) case that the subscription name comes from an untrusted
      source.

      The PostgreSQL Project thanks Yu Kunpeng for reporting this problem.
      (CVE-2026-6476)

    + Properly quote object names in logical replication origin checks
      (Pavel Kohout)

      ALTER SUBSCRIPTION ... REFRESH PUBLICATION interpolated schema and
      relation names into SQL commands without quoting them, allowing
      execution of arbitrary SQL on the publisher.

      The PostgreSQL Project thanks Pavel Kohout for reporting this problem.
      (CVE-2026-6638)

    + Reject over-length options in ts_headline() (Michael Paquier)

      The StartSel, StopSel and FragmentDelimiter strings must not exceed 32Kb
      in length, but this was not checked for.  An over-length value would
      typically crash the server.

      The PostgreSQL Project thanks Xint Code for reporting this problem.
      (CVE-2026-6473)

    + Guard against malicious time zone names in timeofday() and pg_strftime()
      (Tom Lane)

      A crafted time zone setting could pass % sequences to snprintf(),
      potentially causing crashes or disclosure of server memory.  Another
      path to similar results was to overflow the limited-size output buffer
      used by pg_strftime().

      The PostgreSQL Project thanks Xint Code for reporting this problem.
      (CVE-2026-6474)

    + When creating a multirange type, ensure the user has CREATE privilege on
      the schema specified for the multirange type (Jelte Fennema-Nio)

      The multirange type can be put into a different schema than its parent
      range type, but we neglected to apply the required privilege check when
      doing so.

      The PostgreSQL Project thanks Jelte Fennema-Nio for reporting this
      problem. (CVE-2026-6472)

    + Use timing-safe string comparisons in authentication code
      (Michael Paquier)

      Use timingsafe_bcmp() instead of memcpy() or strcmp() when checking
      passwords, hashes, etc.  It is not known whether the data dependency of
      those functions is usefully exploitable in any of these places, but in
      the interests of safety, replace them.

      The PostgreSQL Project thanks Joe Conway for reporting this problem.
      (CVE-2026-6478)

    + Mark PQfn() as unsafe, and avoid using it within libpq (Nathan Bossart)

      For a non-integral result type, PQfn() is not passed the size of the
      output buffer, so it cannot check that the data returned by the server
      will fit.  A malicious server could therefore overwrite client memory.
      This is unfixable without an API change, so mark the function as
      deprecated.  Internally to libpq, use a variant version that can apply
      the missing check.

      The PostgreSQL Project thanks Yu Kunpeng and Martin Heistermann for
      reporting this problem. (CVE-2026-6477)

    + Prevent path traversal in pg_basebackup and pg_rewind (Michael Paquier)

      These applications failed to validate output file paths read from their
      input, so that a malicious source could overwrite any file writable by
      these applications.  Constrain where data can be written by rejecting
      paths that are absolute or contain parent-directory references.

      The PostgreSQL Project thanks XlabAI Team of Tencent Xuanwu Lab and
      Valery Gubanov for reporting this problem. (CVE-2026-6475)

    + Guard against field overflow within contrib/intarray's query_int type
      and contrib/ltree's ltxtquery type (Tom Lane)

      Parsing of these query structures did not check for overflow of 16-bit
      fields, so that construction of an invalid query tree was possible.
      This can crash the server when executing the query.

      The PostgreSQL Project thanks Xint Code for reporting this problem.
      (CVE-2026-6473)

    + Guard against overly long values of contrib/ltree's lquery type
      (Michael Paquier)

      Values with more than 64K items caused internal overflows, potentially
      resulting in stack smashes or wrong answers.

      The PostgreSQL Project thanks Vergissmeinnicht, A1ex, and Jihe Wang for
      reporting this problem. (CVE-2026-6473)

    + Prevent SQL injection and buffer overruns in contrib/spi
      (Nathan Bossart)

      check_foreign_key() was insufficiently careful about quoting key values,
      and also used fixed-length buffers for constructing queries.  While this
      module is only meant as example code, it still shouldn't contain such
      dangerous errors.

      The PostgreSQL Project thanks Nikolay Samokhvalov for reporting this
      problem. (CVE-2026-6637)

  * New upstream version 17.9.

    + Fix failure after replaying a multixid truncation record from WAL that
      was generated by an older minor version (Heikki Linnakangas)

      Erroneous logic for coping with the way that previous versions handled
      multixid wraparound led to replay failure, with messages like "could not
      access status of transaction". A typical scenario in which this could
      occur is a standby server of the latest minor version consuming WAL from
      a primary server of an older version.

    + Avoid incorrect complaint of invalid encoding when substring() is
      applied to toasted data (Noah Misch)

      The fix for CVE-2026-2006 was too aggressive and could raise an error

postgresql-17 (17.8-1) unstable; urgency=medium

  * New upstream version 17.8.

    + Guard against unexpected dimensions of oidvector/int2vector (Tom Lane)

      These data types are expected to be 1-dimensional arrays containing no
      nulls, but there are cast pathways that permit violating those
      expectations.  Add checks to some functions that were depending on those
      expectations without verifying them, and could misbehave in consequence.

      The PostgreSQL Project thanks Altan Birler for reporting this problem.
      (CVE-2026-2003)

    + Harden selectivity estimators against being attached to operators that
      accept unexpected data types (Tom Lane)

      contrib/intarray contained a selectivity estimation function that could
      be abused for arbitrary code execution, because it did not check that
      its input was of the expected data type.  Third-party extensions should
      check for similar hazards and add defenses using the technique intarray
      now uses. Since such extension fixes will take time, we now require
      superuser privilege to attach a non-built-in selectivity estimator to an
      operator.

      The PostgreSQL Project thanks Daniel Firer, as part of zeroday.cloud,
      for reporting this problem. (CVE-2026-2004)

    + Fix buffer overrun in contrib/pgcrypto's PGP decryption functions
      (Michael Paquier)

      Decrypting a crafted message with an overlength session key caused a
      buffer overrun, with consequences as bad as arbitrary code execution.

      The PostgreSQL Project thanks Team Xint Code, as part of zeroday.cloud,
      for reporting this problem. (CVE-2026-2005)

    + Fix inadequate validation of multibyte character lengths
      (Thomas Munro, Noah Misch)

      Assorted bugs allowed an attacker able to issue crafted SQL to overrun
      string buffers, with consequences as bad as arbitrary code execution.
      After these fixes, applications may observe invalid byte sequence for
      encoding errors when string functions process invalid text that has been
      stored in the database.

      The PostgreSQL Project thanks Paul Gerste and Moritz Sanft, as part of
      zeroday.cloud, for reporting this problem. (CVE-2026-2006)

  * New upstream version 17.7.

    + Check for CREATE privileges on the schema in CREATE STATISTICS

      This omission allowed table owners to create statistics in any schema,
      potentially leading to unexpected naming conflicts.

      The PostgreSQL Project thanks Jelte Fennema-Nio for reporting this
      problem. (CVE-2025-12817)

    + Avoid integer overflow in allocation-size calculations within libpq
      (Jacob Champion)

      Several places in libpq were not sufficiently careful about computing
      the required size of a memory allocation.  Sufficiently large inputs
      could cause integer overflow, resulting in an undersized buffer, which
      would then lead to writing past the end of the buffer.

postgresql-17 (17.6-1) unstable; urgency=medium

  * 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.
      (CVE-2025-8713)

    + 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.

    + 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

  * New upstream version 17.4.

    + 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.

  * 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.

    + 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.

      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.

    + 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.

    + 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
