postgresql-14 (14.22-0ubuntu0.22.04.1) jammy-security; urgency=medium

  * New upstream version (LP: #2127668).

    + This release encompasses changes from upstream's 14.21 and 14.22
      releases. The former contains fixes for 4 CVEs (among other things), and
      the latter was a hotfix for regressions introcuced in 14.21.

    + A dump/restore is not required for those running 14.X.

    + However, if you are upgrading from a version earlier than 14.19, see
      those release notes as well please.

    + 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.
      (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. (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.
      (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. (CVE-2026-2006)
