Windows OLE Automation Array Remote Code Execution Vulnerability
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.
