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"
