Source: postgresql-11
Architecture: source
Version: 11.22-0+deb10u1
Distribution: buster-security
Urgency: medium

Changed-By: Christoph Berg <myon@debian.org>
Changes:
 postgresql-11 (11.22-0+deb10u1) buster-security; urgency=medium
 .
   * New upstream version.
 .
     * This is expected to be the last PostgreSQL release in the 11.X series.
       Users are encouraged to update to a newer release branch soon.
 .
     * Fix handling of unknown-type arguments in DISTINCT "any" aggregate
       functions (Tom Lane)
 .
       This error led to a text-type value being interpreted as an unknown-type
       value (that is, a zero-terminated string) at runtime.  This could result
       in disclosure of server memory following the text value.
 .
       The PostgreSQL Project thanks Jingzhou Fu for reporting this problem.
       (CVE-2023-5868)
 .
     * Detect integer overflow while computing new array dimensions
       (Tom Lane)
 .
       When assigning new elements to array subscripts that are outside the
       current array bounds, an undetected integer overflow could occur in edge
       cases.  Memory stomps that are potentially exploitable for arbitrary
       code execution are possible, and so is disclosure of server memory.
 .
       The PostgreSQL Project thanks Pedro Gallegos for reporting this problem.
       (CVE-2023-5869)
 .
     * Prevent the pg_signal_backend role from signalling background workers
       and autovacuum processes (Noah Misch, Jelte Fennema-Nio)
 .
       The documentation says that pg_signal_backend
       cannot issue signals to superuser-owned processes.  It was able to
       signal these background processes, though, because they advertise a
       role OID of zero.  Treat that as indicating superuser ownership.
       The security implications of cancelling one of these process types
       are fairly small so far as the core code goes (we'll just start
       another one), but extensions might add background workers that are
       more vulnerable.
 .
       Also ensure that the is_superuser parameter is set correctly in such
       processes.  No specific security consequences are known for that
       oversight, but it might be significant for some extensions.
 .
       The PostgreSQL Project thanks Hemanth Sandrana and Mahendrakar
       Srinivasarao for reporting this problem. (CVE-2023-5870)
 .
   * Rebase debian/patches/libpgport-pkglibdir.
