DSA-201-1 freeswan -- denial of service

Date Reported:

02 Dec 2002

Affected Packages:

freeswan

Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CVE-2002-0666.
CERT's vulnerabilities, advisories and incident notes: VU#459371.

More information:

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 Debian 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.

Fixed in:

Debian GNU/Linux 3.0 (woody)
