Synopsis:    Moderate: openswan security update
Issue Date:  2011-10-05
CVE Numbers: CVE-2011-3380


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.

A NULL pointer dereference flaw was found in the way Openswan's pluto IKE
daemon handled certain error conditions. A remote, unauthenticated attacker
could send a specially-crafted IKE packet that would crash the pluto
daemon. (CVE-2011-3380)

All users of openswan are advised to upgrade to these updated packages,
which contain a backported patch to correct this issue. After installing
this update, the ipsec service will be restarted automatically.
