Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
A stack-based buffer overflow was found in mtr, possibly resulting in |
| 19 |
the execution of arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
mtr combines the functionality of the 'traceroute' and 'ping' programs |
| 25 |
in a single network diagnostic tool. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |
| 29 |
|
| 30 |
------------------------------------------------------------------- |
| 31 |
Package / Vulnerable / Unaffected |
| 32 |

| 33 |
1 net-analyzer/mtr < 0.73-r1 >= 0.73-r1 |

Description |
| 36 |
=========== |
| 37 |
|
| 38 |
Adam Zabrocki reported a boundary error within the split_redraw() |
| 39 |
function in the file split.c, possibly leading to a stack-based buffer |
| 40 |
overflow. |
| 41 |
|
| 42 |
Impact |
| 43 |
====== |
| 44 |
|
| 45 |
A remote attacker could use a specially crafted resolved hostname to |
| 46 |
execute arbitrary code with root privileges. However, it is required |
| 47 |
that the attacker controls the DNS server used by the victim, and that |
| 48 |
the "-p" (or "--split") command line option is used. |
| 49 |
|
| 50 |
Workaround |
| 51 |
========== |
| 52 |
|
| 53 |
There is no known workaround at this time. |
| 54 |
|
| 55 |
Resolution |
| 56 |
========== |
| 57 |
|
| 58 |
All mtr users should upgrade to the latest version: |
| 59 |
|
| 60 |
# emerge --sync |
| 61 |
# emerge --ask --oneshot --verbose ">=net-analyzer/mtr-0.73-r1" |
| 62 |
