Vulnerability in Windows Shell Could Allow Remote Code Execution (2286198)

A remote code execution vulnerability exists in affected versions of Microsoft Windows. The vulnerability exists because Windows incorrectly parses shortcuts in such a way that malicious code may be executed when the operating system displays the icon of a malicious shortcut file.

Thanks for the heads up, Supernova.

Quick question...

My OS is Win7.

After installing the update and rebooting, I've got the "desktop.ini" file on my desktop. Its content is as following:

[.ShellClassInfo]

LocalizedResourceName=@%SystemRoot%\system32\shell32.dll,-21769

IconResource=%SystemRoot%\system32\imageres.dll,-183

I'm not sure what to do with this file. Can I delete it?

P.S.

I'm using Classic Shell program found here.

P.P.S.

The update can be downloaded and installed via Windows Update site - I get it from there.

The desktop.ini is a system file that stores information about customized folders (e.g. folder background, icon etc) and is safe to delete. These files are usually hidden from view unless you have set Windows Explorer to display hidden/system files (see: Control Panel >> Folder Options).

Thank you, Supernova.
