Microsoft Internet Explorer UTF-8 Decoding Heap Overflow Vulnerability
Improper handling of UTF-8 strings allows attackers to execute arbitrary
code using Internet Explorer.
* Internet Explorer 6 All Versions
* Internet Explorer 5 SP4
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.
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.
Microsoft has issued an update to correct this vulnerability. More details
