  script_tag(name:"insight", value:"This update for postgresql, postgresql15, postgresql16 fixes the following issues:
This update ships postgresql 16.
Security issues fixed:

CVE-2023-5868: Fix handling of unknown-type
 arguments in DISTINCT 'any' aggregate functions. 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. (bsc#1216962)
CVE-2023-5869: Detect integer overflow while
 computing new array dimensions. 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. (bsc#1216961)
CVE-2023-5870: Prevent the pg_signal_backend role
 from signalling background workers and autovacuum processes.
 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.
 (bsc#1216960)
