    Note: If you are using  Ivanti EPM to patch your devices, this issue has been corrected and is only applicable if MS15-092 was installed on your device prior to 7 Dec 2015 and .Net Framework 4.6 is NOT installed on your Windows 8.1 device. From an Ivanti perspective, our Patch and Compliance definition's detection logic has been updated to check for the existence of .NET Framework 4.6 prior to detecting the patch as a vulnerability to the device.

     

    Issue

     

    When attempting to synchronize policies through portal manager on a Windows 8.1 device the following error is displayed:

     

    FailedPolicySync.png

     

    If you're distributing a push or required policy file over to the target, the package won't appear in portal manager. The policysync.exe log file will contain the following error message:

    GetAPMServiceResponse: exception - Method not found: 'Void System.Diagnostics.Tracing.FrameworkEventSource.BeginGetResponse(System.Object, System.String)'

      

     

    Cause

     

    This issue is related to the installation of a Microsoft vulnerability:

    MS15-092_MSU (KB3083185): Vulnerabilities in the .NET Framework could allow elevation of privilege: August 11, 2015

      

     

    Microsoft allows the installation of this vulnerability without the .Net 4.6 framework being installed.

     

    To check for the installation of Microsoft hotfix (KB3083185), conduct the following from an admin command prompt (there are a number of ways to do this, this is simply one method):

     

    systeminfo > systeminfo.txt

     

     

    This will generate a "systeminfo.txt" file from the directory you initiated the command from. Please open up the output file and search for the KB to verify its existence.

     

     

    Resolution

     

    Install Microsoft .Net Framework 4.6 to your affected client device.

     

    .Net Framework 4.6 Installer

     

    If you do not want to install .Net Framework 4.6 in your environment, please ensure your LANDESK patch content is up to date and re-scan your environment to avoid detection of the vulnerability.
