Description Mark J. Cox 2003-10-28 14:25:42 UTC

From bug 107519

If you try to view a group with a posting with a long sender address
pan core dumps.

Version-Release number of selected component (if applicable):
pan-0.13.3-3

How reproducible:
Happens every time.

Steps to Reproduce:
1. Post a message with a long address in From:
2. Try to view the group with pan
    
Actual results:
Pan dumps core

Expected results:
Pan views the group correctly possibly truncating the email address to a
reasonable length.

Additional info:
The bug is listed as security because it is possibly a buffer overflow
that
could potentially be used to execute arbitrary code in every pan
client viewing
the group.

The problem was first seen with a 702 character long email address in the
posting
<mlknecndwmlmnhrntstjauevkcntugtxzvxdvqueiivkcqurmwavvxs.dk>
in
the group dk.test on the server news.tele.dk.

This is a known issue with patch available:
http://bugzilla.gnome.org/show_bug.cgi?id=107025

To follow up on this, the crash causes a null byte to be written to
0x00 which causes a crash but isn't able to be exploited further
(therefore this is limited to a DoS).  Errata in progress.
