Detect integer overflow while computing new array dimensions
|
||||
(Tom Lane)
|
||||
</para>
|
||||
|
||||
<para>
|
||||
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.

Prevent the <literal>pg_signal_backend</literal> role from
|
||||
signalling background workers and autovacuum processes
|
||||
(Noah Misch, Jelte Fennema-Nio)
|
||||
</para>
|
||||
|
||||
<para>
|
||||
The documentation says that <literal>pg_signal_backend</literal>
|
||||
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.
|
||||
</para>
|
||||
|
||||
<para>
|
||||
Also ensure that the <varname>is_superuser</varname> parameter is
|
||||
set correctly in such processes. No specific security consequences
|
||||
are known for that oversight, but it might be significant for some
|
||||
extensions.
