      Date: June 03, 2008
      Bugs: #223017
        ID: 200806-01

Synopsis
=======
A stack-based buffer overflow was found in mtr, possibly resulting in
the execution of arbitrary code.

Background
=========
mtr combines the functionality of the 'traceroute' and 'ping' programs
in a single network diagnostic tool.

Affected packages
================
    -------------------------------------------------------------------
     Package           /  Vulnerable  /                     Unaffected
    -------------------------------------------------------------------
  1  net-analyzer/mtr      < 0.73-r1                        >= 0.73-r1

Description
==========
Adam Zabrocki reported a boundary error within the split_redraw()
function in the file split.c, possibly leading to a stack-based buffer
overflow.

Impact
=====
A remote attacker could use a specially crafted resolved hostname to
execute arbitrary code with root privileges. However, it is required
that the attacker controls the DNS server used by the victim, and that
the "-p" (or "--split") command line option is used.

Workaround
=========
There is no known workaround at this time.

Resolution
=========
All mtr users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-analyzer/mtr-0.73-r1"
