The remote host is missing an update to cpio announced via advisory DSA 664-1.

https://secure1.securityspace.com/smysecure/catid.html?in=DSA%20664-1

It has been discovered, that cpio, a program to manage archives of files, creates output files with -O and -F with broken permissions due to a reset zero umask which allows local users to read or overwrite those files. For the stable distribution (woody) this problem has been fixed in version 2.4.2-39woody1 For the unstable distribution (sid) this problem will be fixed soon. We recommend that you upgrade your cpio package.
