MS13-022: Vulnerability in Microsoft Silverlight Could Allow Remote Code Execution (2814124)

high Nessus Plugin ID 65211
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.

Synopsis

A browser enhancement on the remote Windows host could allow arbitrary code execution.

Description

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.

Solution

Microsoft has released a set of patches for Silverlight 5.
