Description

Openswan is a free implementation of Internet Protocol Security (IPsec)and Internet Key Exchange (IKE). IPsec uses strong cryptography to provideboth authentication and encryption services. These services allow you tobuild secure tunnels through untrusted networks. Everything passing throughthe untrusted network is encrypted by the IPsec gateway machine, anddecrypted by the gateway at the other end of the tunnel. The resultingtunnel is a virtual private network (VPN).Multiple insufficient input validation flaws were found in the wayOpenswan's pluto IKE daemon processed some fields of X.509 certificates. Aremote attacker could provide a specially-crafted X.509 certificate thatwould crash the pluto daemon. (CVE-2009-2185)All users of openswan are advised to upgrade to these updated packages,which contain a backported patch to correct these issues. After installingthis update, the ipsec service will be restarted automatically.
