The issue is related to errors in processing files with .LNK (or .PIF) extensions. Exploitation of this issue can allow a remote attacker to execute arbitrary code using a specially crafted .LNK (or .PIF) file. This can occur when Windows Explorer improperly handles icon display for such files. The issue has been demonstrated in the wild and was originally reported for malware leveraging vulnerabilities in Siemens WinCC SCADA systems. An estimated number of affected devices is not provided, but the issue has been observed in real-world incidents. Technical details include the exploitation of `Windows Shell` in Microsoft Windows, where a crafted (1) `.LNK` or (2) `.PIF` shortcut file is not properly handled during icon display.
