high Nessus Plugin ID 65216
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


A multimedia application framework installed on the remote Mac OS X host is affected a remote code execution vulnerability.


The version of Microsoft Silverlight installed on the remote host reportedly incorrectly checks a memory pointer when rendering an HTML object, which could allow a specially crafted application to access memory in an unsafe fashion.

If an attacker could trick a user on the affected system into visiting a website hosting a malicious Silverlight application, the attacker could leverage this vulnerability to execute arbitrary code on the affected system, subject to the user's privileges.


Microsoft has released a patch for Silverlight 5.
