Synopsis ========
Multiple errors in the IPSec Tools racoon daemon might allow remote attackers to cause a Denial of Service.
Background ==========
The IPSec Tools are a port of KAME's IPsec utilities to the Linux-2.6 IPsec implementation. They include racoon, an Internet Key Exchange daemon for automatically keying IPsec connections.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-firewall/ipsec-tools < 0.7.2 >=3D 0.7.2
Description ===========
The following vulnerabilities have been found in the racoon daemon as shipped with IPSec Tools:
* Neil Kettle reported that racoon/isakmp_frag.c is prone to a null-pointer dereference (CVE-2009-1574).
* Multiple memory leaks exist in (1) the eay_check_x509sign() function in racoon/crypto_openssl.c and (2) racoon/nattraversal.c (CVE-2009-1632).
Impact ======
A remote attacker could send specially crafted fragmented ISAKMP packets without a payload or exploit vectors related to X.509 certificate authentication and NAT traversal, possibly resulting in a crash of the racoon daemon.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All IPSec Tools users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=3Dnet-firewall/ipsec-tools-0.7.2"
