Summary

CVE-1999-1087 is a vulnerability affecting Internet Explorer 4. The issue arises when IE incorrectly interprets a 32-bit number in a URL as a hostname instead of an IP address. This misinterpretation leads to the application of Local Intranet Zone settings to web pages that contain dotless IP addresses. Malicious servers can exploit this vulnerability to conduct unauthorized activities, such as accessing restricted content or installing malware, by using dotless IP addresses in their URLs.
