CVE-2012-1876: Microsoft Internet Explorer

High severity, CVSS 9.3. EPSS: 65% chance of exploitation in the next 30 days.

Microsoft Internet Explorer 6 through 9, and 10 Consumer Preview, does not properly handle objects in memory, which allows remote attackers to execute arbitrary code by attempting to access a nonexistent object, leading to a heap-based buffer overflow, aka "Col Element Remote Code Execution Vulnerability," as demonstrated by VUPEN during a Pwn2Own competition at CanSecWest 2012.

Affected products

• Microsoft Internet Explorer: version 6 only; version 7 only; version 8 only; version 9 only
