Due to simplistic quoting and confusion of database names with conninfo strings, roles with the CREATEDB or CREATEROLE option could escalate to superuser privileges when a superuser next ran certain maintenance commands. The new coding rule for PQconnectdbParams() calls, documented at conninfo_array_parse(), is to pass expand_dbname=true and wrap literal database names in a trivial connection string. Escape zero-length values in appendConnStrVal(). Back-patch to 9.1 (all supported versions). Nathan Bossart, Michael Paquier, and Noah Misch. Reviewed by Peter Eisentraut. Reported by Nathan Bossart. Security: CVE-2016-5424 |

The PostgreSQL contrib tree
---------------------------
This subtree contains porting tools, analysis utilities, and plug-in
features that are not part of the core PostgreSQL system, mainly
because they address a limited audience or are too experimental to be
part of the main source tree. This does not preclude their
usefulness.
User documentation for each module appears in the main SGML
documentation.
When building from the source distribution, these modules are not
built automatically, unless you build the "world" target. You can
also build and install them all by running "gmake all" and "gmake
install" in this directory; or to build and install just one selected
module, do the same in that module's subdirectory.
Some directories supply new user-defined functions, operators, or
types. To make use of one of these modules, after you have installed
the code you need to register the new SQL objects in the database
system by executing a CREATE EXTENSION command. In a fresh database,
you can simply do
CREATE EXTENSION module_name;
See the PostgreSQL documentation for more information about this
procedure.
