The remote host has a version of Java that is affected by multiple vulnerabilities.
The remote Mac OS X host has a version of Java for Mac OS X 10.6 that is missing Update 14, which updates the Java version to 1.6.0_43. It is, therefore, affected by two security vulnerabilities, the most serious of which may allow an untrusted Java applet to execute arbitrary code with the privileges of the current user outside the Java sandbox. Note that an exploit for CVE-2013-1493 has been observed in the wild.
Upgrade to Java for Mac OS X 10.6 Update 14, which includes version 13.9.3 of the JavaVM Framework.
