DESCRIPTION:
A vulnerability has been reported in PostgreSQL, which can be
exploited by malicious people to cause a DoS (Denial of Service).

The vulnerability is caused due to an error in the handling of
multiple concurrent connections. This can be exploited to shutdown
the postmaster process.

Successful exploitation causes a situation where new connections
can't be established until the service is manually restarted.

The vulnerability has been reported in versions 8.0.0 through 8.0.5
and 8.1.0 through 8.1.1. This only affects the Microsoft Windows
platform.

SOLUTION:
Update to version 8.0.6 or 8.1.2.
