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

Microsoft Internet Explorer 6 through 9, and 10 Consumer Preview, allows remote attackers to bypass Protected Mode or cause a denial of service (memory corruption) by leveraging access to a Low integrity process, as demonstrated by VUPEN during a Pwn2Own competition at CanSecWest 2012.

Microsoft Internet Explorer 6.0.2900.2180 and 8.0.7600.16385 allows remote attackers to cause a denial of service (resource consumption) via JavaScript code containing an infinite loop that creates IFRAME elements for invalid news:// URIs.

Microsoft Internet Explorer 6.0.2900.2180, 7, and 8.0.7600.16385 executes a mail application in situations where an IFRAME element has a mailto: URL in its SRC attribute, which allows remote attackers to cause a denial of service (excessive application launches) via an HTML document with many IFRAME elements.

Microsoft Internet Explorer 6.0.2900.2180 and earlier allows remote attackers to cause a denial of service (CPU and memory consumption) via a long Unicode string argument to the write method, a related issue to CVE-2009-2479. NOTE: it was later reported that 7.0.6000.16473 and earlier are also affected.

Stack-based buffer overflow in the AddFavorite method in Microsoft Internet Explorer allows remote attackers to cause a denial of service (application crash) and possibly have unspecified other impact via a long URL in the first argument.

Microsoft Internet Explorer 6.0 and 7.0 allows remote attackers to fill Zones with arbitrary domains using certain metacharacters such as wildcards via JavaScript, which results in a denial of service (website suppression and resource consumption), aka "Internet Explorer Zone Domain Specification Dos and Page Suppressing". NOTE: this issue has been disputed by a third party, who states that the zone settings cannot be manipulated

Unspecified vulnerability in Microsoft Windows 2000 SP4 through Vista allows remote attackers to execute arbitrary code or cause a denial of service (persistent reboot) via a malformed ANI file, which results in memory corruption when processing cursors, animated cursors, and icons, a similar issue to CVE-2005-0416, as originally demonstrated using Internet Explorer 6 and 7. NOTE: this issue might be a duplicate of CVE-2007-0038; if so, then use CVE-2007-0038 instead of this identifier.

Microsoft Internet Explorer 6.0 SP1 on Windows 2000, and 6.0 SP2 on Windows XP, allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via an HTML document containing a certain JavaScript for loop with an empty loop body, possibly involving getElementById.

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.

The Common Controls Replacement Project (CCRP) FolderTreeview (FTV) ActiveX control (ccrpftv6.ocx) allows remote attackers to cause a denial of service (Internet Explorer 7 crash) via a long CCRP.RootFolder property value.

Microsoft Internet Explorer allows remote attackers to cause a denial of service (crash) via an IFRAME with a certain XML file and XSL stylesheet that triggers a crash in mshtml.dll when a refresh is called, probably a null pointer dereference.

Microsoft Internet Explorer 6 SP2 and earlier allows remote attackers to cause a denial of service (crash) via certain malformed HTML, possibly involving applet and base tags without required arguments, which triggers a null pointer dereference in mshtml.dll.

The Microsoft Office Outlook Recipient ActiveX control (ole32.dll) in Windows XP SP2 allows remote attackers to cause a denial of service (Internet Explorer 7 hang) via crafted HTML.

Microsoft Internet Explorer 6 and earlier allows remote attackers to cause a denial of service (application hang) via a CSS-formatted HTML INPUT element within a DIV element that has a larger size than the INPUT.

Microsoft Internet Explorer allows remote attackers to cause a denial of service (memory corruption) and possibly execute arbitrary code by instantiating certain Windows 2000 ActiveX COM Objects including (1) ciodm.dll, (2) myinfo.dll, (3) msdxm.ocx, and (4) creator.dll.

Heap-based buffer overflow in DirectAnimation.PathControl COM object (daxctle.ocx) in Microsoft Internet Explorer 6.0 SP1 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a Spline function call whose first argument specifies a large number of points.

Microsoft Internet Explorer 6.0 SP1 allows remote attackers to cause a denial of service (crash) via a long Color attribute in multiple DirectX Media Image DirectX Transforms ActiveX COM Objects from (a) dxtmsft.dll and (b) dxtmsft3.dll, including (1) DXImageTransform.Microsoft.MaskFilter.1, (2) DXImageTransform.Microsoft.Chroma.1, and (3) DX3DTransform.Microsoft.Shapes.1.

The Terminal Services COM object (tsuserex.dll) allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code by instantiating it as an ActiveX object in Internet Explorer 6.0 SP1 on Microsoft Windows 2003 EE SP1 CN.

Microsoft Internet Explorer 6.0 SP1 and possibly other versions allows remote attackers to cause a denial of service and possibly execute arbitrary code by instantiating COM objects as ActiveX controls, including (1) imskdic.dll (Microsoft IME), (2) chtskdic.dll (Microsoft IME), and (3) msoe.dll (Outlook), which leads to memory corruption. NOTE: it is not certain whether the issue is in Internet Explorer or the individual DLL files.

Microsoft Internet Explorer 6 on Windows XP SP2 allows remote attackers to cause a denial of service (crash) via a (1) Forms.ListBox.1 or (2) Forms.ListBox.1 object with the ListWidth property set to (a) 0x7fffffff, which triggers an integer overflow exception, or to (b) 0x7ffffffe, which triggers a null dereference.

Stack-based buffer overflow in NDFXArtEffects in Microsoft Internet Explorer 6 on Windows XP SP2 allows remote attackers to cause a denial of service (crash) via long (1) RGBExtraColor, (2) RGBForeColor, and (3) RGBBackColor properties.

Internet Explorer 6 on Windows XP SP2, when Outlook is installed, allows remote attackers to cause a denial of service (crash) by calling the NewDefaultItem function of an OVCtl (OVCtl.OVCtl.1) ActiveX object, which triggers a null dereference.

Heap-based buffer overflow in URLMON.DLL in Microsoft Internet Explorer 6 SP1 on Windows 2000 and XP SP1, with versions the MS06-042 patch before 20060912, allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a long URL in a GZIP-encoded website that was the target of an HTTP redirect, due to an incomplete fix for CVE-2006-3869.

Heap-based buffer overflow in URLMON.DLL in Microsoft Internet Explorer 6 SP1 on Windows 2000 and XP SP1, with versions the MS06-042 patch before 20060824, allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a long URL on a website that uses HTTP 1.1 compression.

Integer overflow in Microsoft Internet Explorer 6 on Windows XP SP2 allows remote attackers to cause a denial of service (crash) and execute arbitrary code via a 0x7fffffff argument to the setSlice method on a WebViewFolderIcon ActiveX object, which leads to an invalid memory copy.
