Internet Explorer 10 and 11 Memory Corruption Vulnerability

IdentifiersCVE-2015-0035CWE-119

CVE-2015-0035 is a memory corruption vulnerability in Microsoft Internet Explorer 10 and 11. According to the provided content, the flaw can be triggered when a user visits a specially crafted web page, causing Internet Explorer to improperly handle objects in memory. Successful exploitation may allow a remote attacker to execute arbitrary code in the context of the current user, or cause a denial of service through memory corruption. Microsoft addressed this issue as part of Security Update 3034682, which broadly modified how Internet Explorer handles objects in memory.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation can result in remote code execution with the privileges of the current user. If the user is running with administrative rights, the attacker may be able to fully compromise the affected system. The vulnerability can also be used to cause denial of service via memory corruption. Client systems are at higher risk, while affected server systems are somewhat mitigated by Internet Explorer Enhanced Security Configuration.

Mitigation

If you can’t patch tonight, do this now.

No specific workaround or mitigating factor for the memory corruption vulnerabilities was identified in the provided content. Practical risk reduction measures include limiting use of Internet Explorer for untrusted browsing, operating users without administrative privileges, and relying on Internet Explorer Enhanced Security Configuration on Windows Server systems where applicable. Preventing users from visiting untrusted or attacker-controlled web content also reduces exposure, but does not replace patching.

Remediation

Patch, then assume compromise.

Apply Microsoft's February 2015 Internet Explorer security updates associated with Security Update 3034682. Based on the provided content, systems running Internet Explorer 9, 10, and 11 required both update 3021952 and update 3034196 for full protection, with Microsoft noting installation-order requirements for manual deployment. Organizations should ensure all relevant cumulative Internet Explorer updates and any automatically installed prerequisite or companion updates are fully deployed on affected Windows platforms.
