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 >= 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 ">=net-firewall/ipsec-tools-0.7.2" References ========== [ 1 ] CVE-2009-1574 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1574 [ 2 ] CVE-2009-1632 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1632 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200905-03.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
