remote host is prior to 8 Update 73, 7 Update 97, or 6 Update 113. It
is, therefore, affected by an arbitrary code execution vulnerability
that may have been exploited when installing Java. If an attacker
convinced a user to download a set of malicious files before Java was
installed, then arbitrary code may have been executed during the
installation. A system with the vulnerable versions of Java installed
should be checked for malicious software or abnormal behaviors.");
