Use-after-free RCE in Microsoft Internet Explorer 6-8 CButton/CDwnBindInfo handling
CVE-2012-4792 is a use-after-free vulnerability in Microsoft Internet Explorer 6 through 8 that can be triggered by a specially crafted web page. The provided content describes the flaw as involving improper object lifetime handling in IE's mshtml engine, including cases where an object was not properly allocated or had already been deleted, with public reporting referencing CDwnBindInfo and CERT/CC advisory text identifying the vulnerable area as the mshtml CButton object. Specially crafted JavaScript can cause Internet Explorer to free the object without clearing all references, leaving a dangling pointer that is later dereferenced, resulting in access to an invalid memory address. The vulnerability was exploited in the wild in December 2012, and observed exploit chains used Adobe Flash for heap spraying and Java for ROP gadgets, although proof-of-concept exploits also existed without heap spraying.
