CVE-2010-3971: Use-after-free vulnerability in the CSharedStyleSheet::Notify function in the Cascading Style Sheets (CSS)...

Use-after-free vulnerability in the CSharedStyleSheet::Notify function in the Cascading Style Sheets (CSS) parser in mshtml.dll, as used in Microsoft Internet Explorer 6 through 8 and other products, allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a self-referential @import rule in a stylesheet, aka "CSS Memory Corruption Vulnerability."

Security readout for executives and security teams

This is an old Internet Explorer memory-corruption flaw. A malicious webpage or stylesheet could make affected IE versions crash or potentially run attacker-controlled code. The main business risk is legacy systems that still use Internet Explorer 6 through 8 or products that embed Microsoft’s mshtml.dll rendering engine. Exposure is most likely on legacy Windows endpoints, kiosks, industrial workstations, or embedded applications that still rely on IE 6, 7, 8, or mshtml.dll. The provided affected-product data is incomplete and does not identify every downstream product. Prioritize remediation if any legacy IE or mshtml-dependent systems remain in production. If those systems are gone, this is mainly a historical vulnerability to confirm closed during legacy asset reviews. Mitigation focus: Apply Microsoft’s MS11-003 security update where applicable.; Retire or isolate Internet Explorer 6 through 8 systems.; Identify third-party products that embed mshtml.dll and check vendor guidance..
