"The version of PostgreSQL installed on the remote host is 10.x prior to 10.9 or 11.x prior to 11.4. As such, it is
potentially affected by a stack overflow vulnerability. Any authenticated user can overflow a stack-based buffer by
changing the user's own password to a purpose-crafted value.

Note that Nessus has not tested for this issue but has instead relied only on
the application's self-reported version number.");
