IPSec Tools: Denial of service

IPSec Tools: Denial of service Multiple errors in the IPSec Tools racoon daemon might allow remote attackers to cause a Denial of Service. ipsec-tools 2009-05-24 2009-05-24 267135 remote 0.7.2 0.7.2

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.

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).

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.

There is no known workaround at this time.

All IPSec Tools users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-firewall/ipsec-tools-0.7.2"
