Microsoft Issues Advisory For Internet Explorer Vulnerability

jones_supa (887896) writes "Neowin reports how Microsoft made a rare weekend post on its Security Response Center blog to announce an advisory that affects all currently supported versions of Internet Explorer (versions 6 to 11). The issue is based on a newly discovered exploit that could be used against the web browser. The vulnerability exists in the way that IE accesses an object in memory that has been deleted or has not been properly allocated. Memory may be corrupted in a way that could allow an attacker to execute arbitrary code in the context of the current user. Microsoft is aware of 'limited, targeted attacks' that have used the exploit. IE 10 and 11 are protected against attacks using this exploit if they have their Enhanced Protected Mode turned on. Also, PCs that have either the Enhanced Mitigation Experience Toolkit 4.1 or the EMET 5.0 Technical Preview installed are also secured against this security hole. Microsoft will take the appropriate action to protect its customers by delivering a security update."

      You need to learn Microsoft's various levels of support so you aren't talking out of your ass. Extended support is what comes after mainstream support. Mainstream support is when the OS gets new features, functionality, and new versions of packaged software like IE and WMP via Windows Update. When the product goes into extended support, you only get security patches and bug fixes, but nothing new. Extended support is still free for anyone with a valid license. Extended support is what just ended for XP, five years after mainstream support ended in April 2009. Vista is in extended support for another 3 years. Windows 7 is still in mainstream support until the start of next year after which it goes into extended support until sometime in 2020. After ended support comes the custom paid support where you can still get security patches and bug fixes for a price. I don't know how long Microsoft will keep that up, but my guess is that if you have deep enough pockets Microsoft will support you for a long time.

      I guess the whole point of this discussion is that Microsoft still has versions of Windows with IE6 & 7 in extended support for another couple of years. Considering that IE6 came out in 2001 and installs as far back as Windows 98 that's an incredibly long time for a web browser.

      Actually, C does not try to handle pointers at all. It treats them just like a long int (with the appropriate cast) [...].

      That's not actually true. First of all, there is no direct connection between the size of pointers and the size of long int. That is platform and implementation dependent. Secondly, at compile-time, pointer arithmetic differs a lot from that of integers. You cannot add two pointers. You can subtract two pointers to the same type (except void); that will give you the number of elements between them, in the ptrdiff_t type. (In theory, that's only possible if the pointers point to the same array, but the compiler can't know if that's true in the general case.) You can add an integer to a non-void pointer. Adding N to a pointer p is the same as &p[N], i.e. you get a pointer to the Nth element.

      That's a great question. You can't even use a naive "telnet getfirefox.com 80"... that'll just get you a 403 forbidden! If you include the "Host: getfirefox.com", then it'll give you a redirect to https://www.mozilla.org/firefo...
      NOTE: that's https... if you try to go to the non-ssl version, it just redirects to the HTTPS again. So you can't get that without something like "openssl s_client -connect www.mozilla.org:443", and I don't think you'll find that on windows.

      ftp works with a little digging through ftp.mozilla.org (assuming you know that url). Finding the binary is pretty easy. One needs to know some basics, but it's one of the easiest protocols out there. Ok for a median user? probably not. But it IS an option.
