The vServer with OpenSwan was running since spring 2009, but with a custom kernel and no modules.

Hm, lsmod in the vServer shows me all modules and the modules directory is bind mounted into the vServer.
Thanks for hint to the CVEs. I instantly checked the Debian and Openswan changelogs. Debian had patched the security fixes into the 2.4.12 version. Debian does not change the version number in the stable tree, instead they add their own string to point out that only security fixes were added.

You are right. The correct version is 2.4.12+dfsg-1.3+lenny2. That happens when testing on to many different machines. :)
