CVE-2005-4269: Microsoft Ie

High severity, CVSS 7.8. EPSS: 4.9% chance of exploitation in the next 30 days.

mshtml.dll in Microsoft Windows XP, Server 2003, and Internet Explorer 6.0 SP1 allows attackers to cause a denial of service (access violation) by causing mshtml.dll to process button-focus events at the same time that a document is reloading, as seen in Microsoft Office InfoPath 2003 by repeatedly clicking the "Delete" button in a repeating section in a form. NOTE: the normal operation of InfoPath appears to involve a local user without any privilege boundaries, so this might not be a vulnerability in InfoPath. If no realistic scenarios exist for this problem in other products, then perhaps it should be excluded from CVE.

Affected products

• Microsoft Ie: version 6.0 only
• Microsoft Windows 2003 Server: version r2 only
• Microsoft Windows XP: any version
