Internet Explorer 5.x and 6.0 allows remote attackers to execute arbitrary programs via a modified directory traversal attack using a URL containing ".." (dot dot) sequences and a filename that ends in "::" which is treated as a .chm file even if it does not have a .chm extension. NOTE: this bug may overlap CVE-2004-0475.
