Package        : freeswan
Vulnerability  : denial of service
Problem-type   : remore
Debian-specific: no
CERT advisory  : VU#459371

Bindview discovered a problem in several IPSEC implementations that do
not properly handle certain very short packets.  IPSEC is a set of
security extensions to IP which provide authentication and encryption.
Free/SWan in Debain is affected by this and is said to cause a kernel
panic.

This problem has been fixed in version 1.96-1.4 for the current stable
distribution (woody) and in version 1.99-1 for the unstable
distribution (sid).  The old stable distribution (potato) does not
contain Free/SWan packages.

We recommend that you upgrade your freeswan package.

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
