It seems this report got turned into a CVE for Openswan, CVE-2011-2147

http://www.securityfocus.com/bid/47958/info
http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2011-2147

If debian is still shipping openswan-2.2 unpatched anywhere (released
January 2005) this could be a problem, albeit an extremely minor
one compared to the actual two CVE issues that have come up in openswan
since then. We hope that any openswan-2.2 version that is in active use
has at least gotten some serious looking at based on the security releases
that have since been made.

openswan 2.6.x on debian/ubuntu and fedora/rhel/centos create a read-only
file in /var/locl/subsys.

If someone finds an issue that is actually a security issue, and they
deem it worthy of a CVE release, we strongly encourage those people to
contact us beforehand so we can do a proper responsible vulnerability
disclosure. We also strongly recommend that the CVE people at least attempt
to make an attempt to contact a vendor before releasing vulnerabilities
to the public. We don't bite, honest!

It looks as if someone or some company was in need of reaching their
CVE quota of the month. It would be a shame if future CVE announcements
would get ignored because of too many CVE releases on 6 year old software
releases.
