The issue is related to the improper handling of file operations by the Windows Backup Service, which can lead to an elevation of privilege. To exploit this, an attacker must first gain execution on the victim system. This can potentially allow an attacker to increase their privileges using a specially crafted application.

This issue allows remote attackers to execute arbitrary code on affected installations. User interaction is required, where the target must visit a malicious page or open a malicious file. The flaw exists within the processing of TIF files due to the lack of proper validation of user-supplied data, resulting in a type confusion condition. An attacker can leverage this to execute code in the context of the current process.
