Overview

A remote code execution vulnerability has been reported in Microsoft

Windows, which could allow an attacker to gain the same user rights as the

local user.

Description

This vulnerability exists in Microsoft Windows due to incorrect processing

of the ".LNK" file. An attacker could exploit this vulnerability by

presenting to the user a removable drive, or remote share, that contains a

malicious ".LNK" file and an associated malicious binary. When the user

opens this removable drive (or remote share) in Windows Explorer, or any

other application that parses the ".LNK" file, the malicious code will be

executed by the associated binary on the target system. 

Successful exploitation of this vulnerability would allow to gain same user

rights as the local user.
