Vulnerability Description	There exists a code execution vulnerability in Microsoft Windows Explorer. The vulnerability is due to insecure design in the way Microsoft Windows Explorer parses and saves saved-search(.search-ms) files. Unauthenticated remote attackers can exploit this vulnerability by enticing the target user to open a crafted file and save it, potentially causing arbitrary code to be injected and executed in the security context of the currently logged on user. An attack targeting this vulnerability may result in execution of code. If code execution is successful, the behavior of the target will depend on the intention of the attacker. In the case of an unsuccessful code execution attack, affected product will terminate abnormally resulting in a denial of service condition.
