Microsoft Internet Explorer HTML Object Memory Corruption Use-After-Free
CVE-2010-0249 is a use-after-free memory corruption vulnerability in Microsoft Internet Explorer 6, 6 SP1, 7, and 8. A deleted object can still be referenced through a stale pointer due to improper handling of objects in memory and incorrectly initialized memory. Microsoft and related reporting describe the issue as an invalid pointer access after an object has been deleted, also referred to as the "HTML Object Memory Corruption Vulnerability." Successful exploitation can be triggered by malicious web content, including a specially crafted HTML page, and some advisories also note a Microsoft Office document as a delivery vector for the malicious HTML content. The flaw was exploited in the wild in late 2009 and early 2010, including during Operation Aurora.
