This is going to have an impact on availability. The summary by CVE is:

Multiple ActiveX controls in Microsoft Windows 2000, XP, 2003, and Vista allows remote attackers to cause a denial of service (Internet Explorer crash) by accessing the bgColor, fgColor, linkColor, alinkColor, vlinkColor, or defaultCharset properties in the (1) giffile, (2) htmlfile, (3) jpegfile, (4) mhtmlfile, (5) ODCfile, (6) pjpegfile, (7) pngfile, (8) xbmfile, (9) xmlfile, (10) xslfile, or (11) wdfile objects in (a) mshtml.dll; or the (12) TriEditDocument.TriEditDocument or (13) TriEditDocument.TriEditDocument.1 objects in (b) triedit.dll, which cause a NULL pointer dereference.
