earlier than 8.0 / 7.0.9 / 6.0.6 and reportedly fails to properly
sanitize input to the 'FDF', 'XML', or 'XFDF' fields used by its 'Open
Parameters' feature. By tricking a user into accessing a specially
crafted link and depending on the browser with which the plugin is
used, a remote attacker may be able to leverage these issues to
conduct arbitrary code execution, denial of service, cross-site script
forgery, or cross-site scripting attacks against a user on the remote
host.");
