Descriptions

Heap-based buffer overflow in Microsoft Internet Explorer 5.01 SP4 and 6 SP1 and earlier allows remote attackers to execute arbitrary code via crafted UTF-8 encoded HTML that results in size discrepancies during conversion to Unicode, aka "HTML Decoding Memory Corruption Vulnerability."

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Internet Explorer. Successful exploitation requires that the target user browse to a malicious web page. Exploitaton does not require JavaScript, Java or ActiveX to be enabled.
The specific vulnerability is due to a miscalculation of memory sizes when translating UTF-8 characters to Unicode. A size mismatch between a heap allocation and memory copy results in an exploitable heap corruption.
