+ Openswan is an implementation of IPsec for Linux. IPsec-Tools is a port + of KAME's implementation of the IPsec utilities, including racoon, an + Internet Key Exchange daemon. Internet Key Exchange version 1 (IKEv1), + a derivate of ISAKMP, is an important part of IPsec. IPsec is widely + used to secure exchange of packets at the IP layer and mostly used to + implement Virtual Private Networks (VPNs). +

+
+ +

+ The Oulu University Secure Programming Group (OUSPG) discovered that + various ISAKMP implementations, including Openswan and racoon (included + in the IPsec-Tools package), behave in an anomalous way when they + receive and handle ISAKMP Phase 1 packets with invalid or abnormal + contents. +

+
+ +

+ A remote attacker could craft specific packets that would result in a + Denial of Service attack, if Openswan and racoon are used in specific, + weak configurations. +

+
+ +

+ There is no known workaround at this time. +

+
+ +

+ All Openswan users should upgrade to the latest version: +

+ + # emerge --sync + # emerge --ask --oneshot --verbose ">=net-misc/openswan-2.4.4" +

+ All IPsec-Tools users should upgrade to the latest version: +

+ + # emerge --sync + # emerge --ask --oneshot --verbose net-firewall/ipsec-tools +
