CVE-2011-0346: Use-after-free vulnerability in the ReleaseInterface function in MSHTML.DLL in Microsoft Internet Explorer...

Use-after-free vulnerability in the ReleaseInterface function in MSHTML.DLL in Microsoft Internet Explorer 6, 7, and 8 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via vectors related to the DOM implementation and the BreakAASpecial and BreakCircularMemoryReferences functions, as demonstrated by cross_fuzz, aka "MSHTML Memory Corruption Vulnerability."

Security readout for executives and security teams

CVE-2011-0346 is a memory corruption flaw in Internet Explorer’s MSHTML engine. A remote attacker could cause code execution or a browser crash through crafted DOM-related content. Business urgency is highest where legacy Internet Explorer 6, 7, or 8 remains in use, especially on systems that browse untrusted sites. Exposure is most likely on legacy Windows endpoints or embedded workflows still using Internet Explorer 6, 7, or 8. The bundle’s affected-product metadata is incomplete, but the CVE description identifies those IE versions. Prioritize remediation if any legacy Internet Explorer use remains. The vulnerability enables remote code execution, but scope is concentrated in obsolete browser versions. If no IE 6-8 assets exist, document non-exposure and monitor only legacy exceptions. Mitigation focus: Apply Microsoft MS11-018 security updates where applicable.; Remove or replace Internet Explorer 6, 7, and 8 from operational workflows.; Isolate legacy systems that cannot be updated..
