Debian Security Advisory DSA 201-1 security@debian.org

December 2nd, 2002 http://www.debian.org/security/faq

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.
