Details

Akio Ishida discovered that the SET SESSION AUTHORIZATION command did
not properly verify the validity of its argument. An authenticated
PostgreSQL user could exploit this to crash the server.

However, this does not affect the official binary Ubuntu packages. The
crash can only be triggered if the source package is rebuilt with
assertions enabled (which is not the case in the official binary
packages).
