MS12-016: Vulnerabilities in .NET Framework and Microsoft Silverlight Could Allow Remote Code Execution (2651026)

high Nessus Plugin ID 57950
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

The .NET Framework install on the remote Windows host could allow arbitrary code execution.

Description

The version of the .NET Framework installed on the remote host reportedly is affected by the following vulnerabilities :

- The .NET Framework and Silverlight do not properly use unmanaged objects, which could allow a malicious .NET Framework application to access memory in an unsafe manner. (CVE-2012-0014)

- The .NET Framework does not properly calculate a buffer length when processing malicious input, which could lead to heap corruption. (CVE-2012-0015)

An attacker may be able to leverage these vulnerabilities to execute arbitrary code on the affected system if a user on it can be tricked into viewing a specially crafted web page using a web browser that can run XAML Browser Applications (XBAPs) or Silverlight applications.

Solution

Microsoft has released a set of patches for .NET Framework 2.0, 3.5.1, and 4 as well as Silverlight 4.
