0-day exploit in IE7
In addition to the post: New attack on an unclosed flaw in IE browser
0-day-exploits are those vulnerabilities that are detected by hackers and for which no fixes have yet been released or about which nothing is known to the appropriate security agencies of companies whose products have found gaps.
It turns out that the “security hole” of IE7 “sensational” in the last days was not eliminated in yesterday's patch (08.12.2008) MS08-073. This means that this vulnerability is currently present in fully patched Windows XP.

An exploit based on heap overflow, this attack is known as heap overflow, affecting the browser's XML parser. After installing the heap with the shell-code, the exploit checks the ability to work. For the "successful" operation of the exploit requires a browser IE7 and Windows XP or Windows 2003.
This is followed by a small delay of a few seconds, which allows you to fool antiviruses, and the malicious code is executed.
It should be noted that the codes for this exploit are publicly available on many information security sites. This indicates a high probability of massive attacks of this kind, including from the script kiddie. Be carefull!
