Hi ethereal developers,
Recently I started to use Ethereal for diagnose problems on network I
administer, but I found some bug in this software. In fact I'm not
sure wheather this bug is in Ethereal itself or somewhere else (gtk?)
Now, what happened:
I started to look into one of LDAP packet.
I have it in file "_bug" (see attachment).
The tree looks like this:
Tree looks like this:
------------------- cut ------------------------
...
[-] Lightweight Directory Access Protocol
Request Line: 09c4CLID_IP
Request Line:
Request Line:
------------------- cut ------------------------
2nd and 3rd request lines are realy empty.
And this is contents of LDAP packet I can see in bottom frame:
------------------- cut -------------------------------------------------

I'm not very familiar with LDAP packets, but it seems to not be OK.
I think decoding from packet itself to tree is incorrect.
Then:
First expand the LDAP subtree.
Second select lets say one of the request line.
In this time Ethereal crashes.
(sometime crashes sometime not. On my second computer crashes
almost everytime)
In addition,
If I try to run it within gdb it looks like this:
(gdb) run
Starting program: /home/mstekrt/ethereal/./ethereal
Program received signal SIGSEGV, Segmentation fault.
0x40142f7c in gtk_text_forward_delete () from /usr/lib/libgtk-1.2.so.0
Imediately after, it blocks my mouse. I cannot select
anything and cursor has arrow shape. Cannot select window frames nor
taskbar. In this time Ethereal window is stil existing on desktop,
but doesn't redraw itself.
(gdb) backtrace
#0 0x40142f7c in gtk_text_forward_delete () from /usr/lib/libgtk-1.2.so.0
#1 0x40192ed8 in GTK_TYPE_GDK_COLOR () from /usr/lib/libgtk-1.2.so.0
#2 0x10fc8 in ?? ()
#3 0x0 in ?? ()
(gdb) quit
The program is running. Exit anyway? (y or n) y
[mstekrt@e210 ethereal]$
Then mouse works again.
These are my version:
uname -sr
Linux 2.2.12-20
gtk-config --version
1.2.6
./ethereal -v
ethereal 0.8.1, with GTK+ 1.2.6, with libpcap 0.4, with libz 1.1.3,
with UCD SNMP 4.0.1
KDE 1.1.2
Thanks for Ethereal
