Internet Explorer 10 and 11 Memory Corruption Vulnerability

IdentifiersCVE-2015-0068CWE-119

CVE-2015-0068 is a memory corruption vulnerability in Microsoft Internet Explorer 10 and 11. According to the provided content, a remote attacker can trigger the flaw by luring a user to visit a specially crafted web page, including via a malicious site, a compromised legitimate site, or malicious advertising content. The vulnerability is described by Microsoft as an "Internet Explorer Memory Corruption Vulnerability" and is distinct from CVE-2015-0027, CVE-2015-0035, CVE-2015-0039, and CVE-2015-0052. Successful exploitation can result in arbitrary code execution or denial of service due to memory corruption. Microsoft’s broader bulletin states that these issues were addressed by changing 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 allow remote code execution in the security context of the current user. If the victim is logged on with administrative privileges, the attacker may be able to fully compromise the affected system. The content also states that the vulnerability may be used to cause denial of service through memory corruption. Workstations and other systems used for routine web browsing are at higher risk than hardened server deployments.

Mitigation

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

The provided content states that Microsoft identified no specific workarounds or mitigating factors for the memory corruption vulnerabilities. Practical exposure reduction includes limiting user privileges and reducing browsing exposure to untrusted content. On Windows Server platforms, Internet Explorer Enhanced Security Configuration reduces exposure to specially crafted web content and was noted as a factor in Microsoft’s lower severity rating for server systems.

Remediation

Patch, then assume compromise.

Apply Microsoft Security Update 3034682 and associated Internet Explorer updates required for the affected platform. The provided content states that for Internet Explorer 9, 10, and 11, both update 3021952 and update 3034196 were required for full protection, with 3021952 needing to be installed before 3034196 when installed manually. On some platforms, installing 3021952 also installs updates 3023607 and 3036197 automatically. Remediation is achieved by updating Internet Explorer’s memory handling to correct the underlying flaw.
