    (reposting again with the hole history)
    Andres Tarasco of sia.es has published yesterday a security hole affecting
    BadBlue 2.5 and below.

    http://seclists.org/lists/fulldisclosure/2005/Feb/0704.html

    Hat-Squad.com brought you a fresh exploit.
    The exploit and BadBlue v2.5 are both available at class101.org for your
    exploitation's pratices, njoy :)

    /*
    BadBlue, Easy File Sharing Remote BOverflow

    Homepage: badblue.com
    Affected version: v2.5 (2.60 and below not tested)
    Patched version: v2.61
    Link: badblue.com/bbs98.exe
    Date: 27 February 2005

    Application Risk: Severely High
    Internet Risk: Low

    Dicovery Credits: Andres Tarasco (atarasco _at_ sia.es)
    Exploit Credits : class101 & metasploit.com

    Hole History:

      26-2-2005: BOF flaw published by Andres Tarasco of sia.es
      27-2-2002: Hat-Squad.com releases an exploit
      28-2-2005: haxorcitos releases a dupe with fake date :>
                 or you sux doing private stuffs.

    Notes:

      -6 bad chars, 0x00, 0x26, 0x20, 0x0A, 0x8C, 0x3C, badly interpreted by
    BadBlue
      -using offsets from ext.dll, universal.
      -use findjmp2 to quick search into ext.dll to see
       if the offsets changes in the others BadBlue's versions below 2.5
      -if you need the v2.5 for exploitation's pratices, get it on class101.org
      -rename to .c for nux, haven't tested this one but it should works fine.
