Windows OLE Automation Array Remote Code Execution Vulnerability

IdentifiersCVE-2014-6332CWE-190

CVE-2014-6332 is a remote code execution vulnerability in Microsoft Windows OLE automation, specifically in OleAut32.dll. The flaw is triggered through improper handling of a size value during SAFEARRAY resizing operations, as described in relation to the SafeArrayDimen/SafeArrayRedim logic. A crafted web page can trigger an array-redimensioning condition that causes incorrect size validation and memory corruption in OLE automation. In practical exploitation, the issue was commonly reached via Internet Explorer rendering attacker-controlled script content, and was widely weaponized in exploit kits and targeted phishing campaigns. Microsoft addressed the issue in MS14-064.

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 allows remote arbitrary code execution in the security context of the current user. If the victim is logged on with administrative privileges, the attacker can fully compromise the affected system. The vulnerability was exploited in the wild as a zero-day and used both for broad exploit-kit delivery and targeted intrusion activity.

Mitigation

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

If immediate patching is not possible, reduce exposure by disabling or restricting active scripting/active content in Internet Explorer and limiting access to untrusted web content. Additional compensating controls include using least-privilege user accounts, hardening browser security settings, and restricting execution paths commonly used by post-exploitation payloads. These measures reduce exploitability but do not eliminate the underlying flaw.

Remediation

Patch, then assume compromise.

Apply Microsoft's security update for MS14-064 on affected Windows systems. Ensure supported versions of Windows and Internet Explorer receive the vendor patch that corrects the OLE automation array size-handling flaw in OleAut32.dll. Standard patch validation and accelerated deployment are warranted because the vulnerability was exploited in the wild.
