Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple errors in the IPSec Tools racoon daemon might allow remote |
| 19 |
attackers to cause a Denial of Service. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
The IPSec Tools are a port of KAME's IPsec utilities to the Linux-2.6 |
| 25 |
IPsec implementation. They include racoon, an Internet Key Exchange |
| 26 |
daemon for automatically keying IPsec connections. |
| 27 |
|
| 28 |
Affected packages |
| 29 |
================= |
| 30 |
|
| 31 |
------------------------------------------------------------------- |
| 32 |
Package / Vulnerable / Unaffected |
| 33 |
------------------------------------------------------------------- |
| 34 |
1 net-firewall/ipsec-tools < 0.7.2 >= 0.7.2 |
| 35 |
|
| 36 |
Description |
| 37 |
=========== |
| 38 |
|
| 39 |
The following vulnerabilities have been found in the racoon daemon as |
| 40 |
shipped with IPSec Tools: |
| 41 |
|
| 42 |
* Neil Kettle reported that racoon/isakmp_frag.c is prone to a |
| 43 |
null-pointer dereference (CVE-2009-1574). |
| 44 |
|
| 45 |
* Multiple memory leaks exist in (1) the eay_check_x509sign() |
| 46 |
function in racoon/crypto_openssl.c and (2) racoon/nattraversal.c |
| 47 |
(CVE-2009-1632). |
| 48 |
|
| 49 |
Impact |
| 50 |
====== |
| 51 |
|
| 52 |
A remote attacker could send specially crafted fragmented ISAKMP |
| 53 |
packets without a payload or exploit vectors related to X.509 |
| 54 |
certificate authentication and NAT traversal, possibly resulting in a |
| 55 |
crash of the racoon daemon. |
| 56 |
|
| 57 |
Workaround |
| 58 |
========== |
| 59 |
|
| 60 |
There is no known workaround at this time. |
| 61 |
|
| 62 |
Resolution |
| 63 |
========== |
| 64 |
|
| 65 |
All IPSec Tools users should upgrade to the latest version: |
| 66 |
|
| 67 |
# emerge --sync |
| 68 |
# emerge --ask --oneshot --verbose ">=net-firewall/ipsec-tools-0.7.2" |
| 69 |
