CVE-2013-3918
Out-of-Bounds Write RCE in Microsoft Windows InformationCardSigninHelper ActiveX

CVE-2013-3918 is an out-of-bounds write vulnerability in the InformationCardSigninHelper Class ActiveX control (icardie.dll) that ships with Internet Explorer on Microsoft Windows. An attacker triggers it by luring a user to a specially crafted web page; when the page invokes the affected ActiveX control, memory is written outside its allocated bounds and remote code execution can result. A successful attacker gains the same privileges as the currently logged-on user, so code executed under an administrator account would run with full administrative rights. Any Windows system with the vulnerable control present is affected — CISA lists 'Microsoft Windows' broadly without specific version ranges, and notes impacted releases may be end-of-life or end-of-service. The flaw has been exploited in the wild since its November 2013 disclosure, was fixed in an out-of-band update at the time, and CISA added it to the KEV catalog on 2025-10-06 with a very high EPSS of 73.9% (probability of exploitation within 30 days).

Do: Apply Microsoft's vendor fix for CVE-2013-3918 — the November 2013 out-of-band Internet Explorer cumulative security update (MS13-090) — or any later cumulative IE update on systems still in service; on systems that cannot be patched, set the killbit/disable the InformationCardSigninHelper ActiveX control or discontinue use of the EoL/EoS Windows releases per CISA guidance. Federal agencies must complete the required action within the BOD 22-01 deadline following the 2025-10-06 KEV addition. Verify that icardie.dll is no longer loadable in Internet Explorer (or IE mode in Edge) and that legacy IE usage is minimized across the estate.

The Microsoft Updates are pretty significant this month. Internet Explorer, which was missing from the updates for the first time in a long time last month is back with a whopping 24 vulnerabilities. Besides the IE bulletin, there’s six more bulletins, 4 of which are rated critical and 3 of which are rated important. All-in-all, this Update Tuesday provides fixes for 32 CVEs. The list of bulletins below is ordered by rating rather than number (i.e., the same ordering as used here: https://technet.microsoft.com/en-us/security/bulletin/ms14-feb).

The first bulletin, MS14-010, deals with IE and is rated critical and provides fixes for 24 CVEs. As is usual, most of the vulnerabilities are the result of use-after-free vulnerabilities. Most of the vulnerabilities were reported privately to Microsoft, but there is also one fix for a publicly disclosed vulnerability (CVE-2014-0267), a use-after-free vulnerability.

The second critical bulletin, MS14-011, provides an update for a vulnerability in VBScript that is shared with the IE bulletin (CVE-2014-0271), where a type confusion vulnerability could lead to arbitrary code execution.

MS14-007 is also rated critical and it fixes a vulnerability in Direct2D (CVE-2014-0263) that could result in remote code execution. The vulnerability can be triggered if a user browses to a malicious website and is presented with a malicious SVG object.

The final critical bulletin this month is MS14-008.This vulnerability occurs in Microsoft’s Forefront Protection 2010 which provides anti-malware and anti-spam protection for Exchange Server. The vulnerability occurs when a specifically crafted email is scanned by the server and could result in remote code execution (CVE-2014-0294). It is unclear if the vulnerability can be triggered and there are currently no known exploitation scenarios for this vulnerability.

Microsoft’s next bulletin, MS14-009 is rated as important and deals with the .NET framework. It is the only bulletin besides IE that compromises multiple CVEs: three in total. Two of these have been publicly disclosed. The first one is a denial of service in ASP.NET that can be triggered via an incomplete POST request (CVE-2014-0253). The second publicly disclosed vulnerability is an ASLR bypass (CVE-2014-0295) due to a lack of ASLR support in VSAVB7RT.DLL. Finally, the last vulnerability in this bulletin is an escalation of privilege vulnerability due to type traversal (CVE-2014-0257).

MS14-005 is also rated as important and provides a fix for a single vulnerability in XML Core Services that could result in a bypass of the same origin policy (CVE-2014-0266). This could allow information disclosure, where an attacker could read local files on disk via a malicious webpage. This information leak was previously used in conjunction with the IE 0-day “Watering hole” vulnerability (CVE-2013-3918), which was patched in a previous update cycle. The information disclosure vulnerability was used to retrieve thetimestamp from the PE headers of msvcrt.dll to allow the attacker to use a ROP chain specific to that version of the DLL.

The last bulletin of the month is MS14-006 and is rated as important. It provides an update for Microsoft’s IPV6 TCP/IP stack, where maliciously crafted IPV6 routing discovery packets sent on the same subnet as the vulnerable machine could result in a denial of service (CVE-2014-0254), which causes the machine to become unresponsive while processing these packets and could possibly crash.

The VRT is releasing the following rules SIDs 23178, 24926, 29655, 29667-29668, 29671-29722, 29727-29738 and 29741-29744 to address these issues.
