RHSA-2009:1138 -- openswan security update (Important)
Updated openswan packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5. This update has been rated as having important security impact by the Red Hat Security Response Team. Openswan is a free implementation of Internet Protocol Security (IPsec) and Internet Key Exchange (IKE). IPsec uses strong cryptography to provide both authentication and encryption services. These services allow you to build secure tunnels through untrusted networks. Everything passing through the untrusted network is encrypted by the IPsec gateway machine and decrypted by the gateway at the other end of the tunnel. The resulting tunnel is a virtual private network (VPN).
