Revised Security Release available for 8.2, 8.1, 8.0

Revised Security Release available for 8.2, 8.1, 8.0

The PostgreSQL Global Development Group releases today a security update for
all PostgreSQL 8.X versions: minor versions 8.2.3, 8.1.8, 8.0.12. This
release replaces the security release from February 5th, which contained a
type-casting bug affecting many users.

If you downloaded a copy of 8.2.2, 8.1.7 or 8.0.11, you should discard that
versions and install the updated versions instead.

This release fixes CVE-2007-0555 and CVE-2007-0556. Both of these issues
allow an authenticated attacker with the permissions to run arbitrary SQL to
launch a denial-of-service attack or possibly read out random chunks of
memory. Since attacks to require authenticated access, the security hole is
only considered medium risk. You can read more about the issues on Mitre:
