Synopsis |
| 19 |
======== |
| 20 |
|
| 21 |
racoon provided as part of IPsec-Tools fails do proper authentication. |
| 22 |
|
| 23 |
Background |
| 24 |
========== |
| 25 |
|
| 26 |
IPsec-Tools is a port of KAME's implementation of the IPsec utilities. |
| 27 |
It contains a collection of network monitoring tools, including racoon, |
| 28 |
ping, and ping6. |
| 29 |
|
| 30 |
Affected packages |
| 31 |
================= |
| 32 |
|
| 33 |
------------------------------------------------------------------- |
| 34 |
Package / Vulnerable / Unaffected |
| 35 |
------------------------------------------------------------------- |
| 36 |
1 net-firewall/ipsec-tools < 0.3.3 >= 0.3.3 |

Description |
| 39 |
=========== |
| 40 |
|
| 41 |
The KAME IKE daemon racoon is used to authenticate peers during Phase 1 |
| 42 |
when using either preshared keys, GSS-API, or RSA signatures. When |
| 43 |
using RSA signatures racoon validates the X.509 certificate but not the |
| 44 |
RSA signature. |
| 45 |
|
| 46 |
Impact |
| 47 |
====== |
| 48 |
|
| 49 |
By sending a valid and trusted X.509 certificate and any private key an |
| 50 |
attacker could exploit this vulnerability to perform man-in-the-middle |
| 51 |
attacks and initiate unauthorized connections. |
| 52 |
|
| 53 |
Workaround |
| 54 |
========== |
| 55 |
|
| 56 |
There is no known workaround at this time. All users are encouraged to |
| 57 |
upgrade to the latest available version. |
| 58 |
|
| 59 |
Resolution |
| 60 |
========== |
| 61 |
|
| 62 |
All IPsec-Tools users should upgrade to the latest stable version: |
| 63 |
|
| 64 |
# emerge sync |
| 65 |
|
| 66 |
# emerge -pv ">=net-firewall/ipsec-tools-0.3.3" |
| 67 |
# emerge ">=net-firewall/ipsec-tools-0.3.3" |
| 68 |
