Description

These services allow you tobuild secure tunnels through untrusted networks.A NULL pointer dereference flaw was found in the way Openswan's pluto IKEdaemon handled certain error conditions. A remote, unauthenticated attackercould send a specially-crafted IKE packet that would crash the plutodaemon. (CVE-2011-3380)Red Hat would like to thank the Openswan project for reporting this issue.Upstream acknowledges Paul Wouters as the original reporter.All users of openswan are advised to upgrade to these updated packages,which contain a backported patch to correct this issue.
