An elevation of privilege vulnerability exists when the Visual Studio Extension Installer Service improperly handles file operations. An attacker who successfully exploited the vulnerability could delete files in arbitrary locations with elevated permissions. To exploit the vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability. The update addresses the vulnerability by correcting how the Visual Studio Extension Installer Service handles file operations.
