    I misread a '1' for an 'l' on the exploit. X blows up quite handily
    now.

    Has anyone see this alert?

    http://www.securityfocus.com/archive/1/353352

    It seems to work on Linux, but when I tried the proof of concept on
    4.3.0,1 running 5.2 RELEASE, I couldn't get the X server to core dump
    or segmentation fault. So, it seems likely to me that FreeBSD is not
    vulnerable to this. Any other thoughts on this matter?
