The remote host is missing an update to geneweb announced via advisory DSA 223-1.

https://secure1.securityspace.com/smysecure/catid.html?in=DSA%20223-1

A security issue has been discovered by Daniel de Rauglaudre, upstream author of geneweb, a genealogical software with web interface. It runs as a daemon on port 2317 by default. Paths are not properly sanitized, so a carefully crafted URL lead geneweb to read and display arbitrary files of the system it runs on. For the current stable distribution (woody) this problem has been fixed in version 4.06-2. The old stable distribution (potato) is not affected. For the unstable distribution (sid) this problem has been fixed in version 4.09-1. We recommend that you upgrade your geneweb package.
