A vulnerability was found in Microsoft Windows Server 2003/XP (Operating System). It has been classified as critical. This affects some unknown functionality in the library mshtml.dll. The manipulation with an unknown input leads to a denial of service vulnerability. CWE is classifying the issue as CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. This is going to have an impact on availability. The summary by CVE is:

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.
