Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
A buffer overflow in noip-updater can lead to arbitrary code execution. |
| 19 |
|
| 20 |
Background |
| 21 |
========== |
| 22 |
|
| 23 |
noip-updater is a tool used for updating IP addresses of dynamic DNS |
| 24 |
records at no-ip.com. |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |
| 28 |
|
| 29 |
------------------------------------------------------------------- |
| 30 |
Package / Vulnerable / Unaffected |
| 31 |
------------------------------------------------------------------- |
| 32 |
1 net-dns/noip-updater < 2.1.9 >= 2.1.9 |
| 33 |
|
| 34 |
Description |
| 35 |
=========== |
| 36 |
|
| 37 |
xenomuta found out that the GetNextLine() function in noip2.c misses a |
| 38 |
length check, leading to a stack-based buffer overflow. |
| 39 |
|
| 40 |
Impact |
| 41 |
====== |
| 42 |
|
| 43 |
A remote attacker could exploit this vulnerability to execute arbitrary |
| 44 |
code by sending a specially crafted HTTP message to the client. NOTE: |
| 45 |
Successful exploitation requires a man in the middle attack, a DNS |
| 46 |
spoofing attack or a compromise of no-ip.com servers. |
| 47 |
|
| 48 |
Workaround |
| 49 |
========== |
| 50 |
|
| 51 |
There is no known workaround at this time. |
| 52 |
|
| 53 |
Resolution |
| 54 |
========== |
| 55 |
|
| 56 |
All noip-updater users should upgrade to the latest version: |
| 57 |
|
| 58 |
# emerge --sync |
| 59 |
# emerge --ask --oneshot --verbose ">=net-dns/noip-updater-2.1.9" |
| 60 |
