Description gallir 2006-02-24 01:03:56 UTC
Version:           3.5.1 (using KDE 3.5.1, Debian Package 4:3.5.1-2 (testing/unstable))
Compiler:          Target: i486-linux-gnu
OS:                Linux (i686) release 2.6.15

I discovered this bug in my konqueror several days ago. Today I confirmed that it occurs in others' computer too.

When a javascript function is called from a timer and execute the following lines (from the file shown below):

if ("undefined" != typeof(mnm_banner_reload) &&  mnm_banner_reload > 100000) {
   setTimeout("write_banner_frame()", mnm_banner_reload);
}

it starts several kio_http processes which in turn open hundred connections  wich result in a DoS of the server during a couple of minutes: (http://mnm.uib.es/gallir/tmp/dos.txt)

What it's strange is that occuers always more or less at the same time: 23:54/55 Spanish time (UTC+1).

Comment 1 Philip Rodrigues 2006-09-25 20:28:35 UTC
Is there a page at which we can see this behaviour?
Comment 2 gallir 2006-09-25 20:46:17 UTC
It occured at http://meneame.net/sneak.php, the code is the same as shown above.

Although I didn't see this bug again in last kde 3.5.4 (Debian Sid).
Comment 3 Frederik Schwarzer 2007-01-06 13:14:40 UTC
I cannot confirm this in 3.5.5 on debian and in up-to-date 3.5 branches.
Comment 4 Jakub Stachowski 2007-01-06 13:27:21 UTC
Works for me on KDE 3.5.5 installed from Kubuntu packages.
Comment 5 Philip Rodrigues 2007-01-06 13:34:53 UTC
Maybe related to bug 104520 (see comment 4 on that report). Needs a developer to comment perhaps)
Comment 6 Jonas Vejlin 2009-04-05 08:18:42 UTC
do you still have this problem in konq 4?
