Microsoft » IE : Security Vulnerabilities, CVEs, Published In 2005 (Denial of service)

Microsoft Internet Explorer 6.0 on Windows NT 4.0 SP6a, Windows 2000 SP4, Windows XP SP1, Windows XP SP2, and Windows Server 2003 SP1 allows remote attackers to cause a denial of service (client crash) via a certain combination of a malformed HTML file and a CSS file that triggers a null dereference, probably related to rendering of a DIV element that contains a malformed IMG tag, as demonstrated by IEcrash.htm and IEcrash.rar.

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.

Microsoft Internet Explorer 5.01, 5.5, and 6 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a web page with embedded CLSIDs that reference certain COM objects that are not intended for use within Internet Explorer, aka a variant of the "COM Object Instantiation Memory Corruption Vulnerability," a different vulnerability than CVE-2005-2127.

The JPEG decoder in Microsoft Internet Explorer allows remote attackers to cause a denial of service (CPU consumption or crash) and possibly execute arbitrary code via certain crafted JPEG images, as demonstrated using (1) mov_fencepost.jpg, (2) cmp_fencepost.jpg, (3) oom_dos.jpg, or (4) random.jpg.

Internet Explorer 5.01 SP4 up to 6 on various Windows operating systems, including IE 6.0.2900.2180 on Windows XP, allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a web page with embedded CLSIDs that reference certain COM objects that are not ActiveX controls, as demonstrated using the JVIEW Profiler (Javaprxy.dll). NOTE: the researcher says that the vendor could not reproduce this problem.

Internet Explorer 5.0, 5.5, and 6.0 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a web page with embedded CLSIDs that reference certain COM objects that are not ActiveX controls, including (1) devenum.dll, (2) diactfrm.dll, (3) wmm2filt.dll, (4) fsusd.dll, (5) dmdskmgr.dll, (6) browsewm.dll, (7) browseui.dll, (8) shell32.dll, (9) mshtml.dll, (10) inetcfg.dll, (11) infosoft.dll, (12) query.dll, (13) syncui.dll, (14) clbcatex.dll, (15) clbcatq.dll, (16) comsvcs.dll, and (17) msconf.dll, which causes memory corruption, aka "COM Object Instantiation Memory Corruption Vulnerability," a different vulnerability than CVE-2005-2087.
