Windows OLE Automation Array Remote Code Execution Vulnerability
CVE-2014-6332 is a remote code execution vulnerability in OleAut32.dll within Microsoft Windows OLE/OLE Automation. The flaw is triggered through improper handling of a size value during SAFEARRAY resizing operations, specifically in the SafeArrayDimen/SafeArrayRedim code path as described in the provided content. A crafted web page can trigger an array-redimensioning condition that causes incorrect size validation and unsafe memory handling, leading to arbitrary code execution. The issue affected multiple Windows client and server versions and was commonly exploited through Internet Explorer, including in exploit kits and watering-hole attacks.
