- 漏洞描述

Internet Explorer contains a flaw that may allow a remote denial of service. The issue is triggered when a victim right clicks then chooses "Save As" on a specially crafted URL. When this happens Internet Explorer tries to download the non-existent file, which fails causing it to try to report an error. This error report fails when FormatMessageW calls RtlFormatMessage and passes a pointer to an array (Array1) which does not exist due to the malicious URL. The end result is a loss of availability for Internet Explorer.
