PostgreSQL Character Conversion and Tsearch2 Module Vulnerabilities

Vulnerability Assessment Summary
Checks for character conversion and tsearch2 module vulnerabilities in PostgreSQL

Detailed Explanation for this Vulnerability Assessment

Summary :

The remote database server is affected by multiple vulnerabilities.

Description :

According to its banner, the version of PostgreSQL installed on the
remote host may suffer from the following vulnerabilities :

- Character Conversion Vulnerability
Unprivileged users can call functions supporting client-
server character set conversion from SQL commands even
though those functions do not validate their arguments.

- tsearch2 Vulnerability
If installed, the 'contrib/tsearch2' module permits users
to at a minimum crash the backend because it misdeclares
several functions as returning type 'internal' when in
fact they do not have any 'internal' argument.
