The remote host is missing an update to roundup announced via advisory DSA 1754-1.

https://secure1.securityspace.com/smysecure/catid.html?in=DSA%201754-1

It was discovered that roundup, an issue tracker with a command-line, web and email interface, allows users to edit resources in unauthorized ways, including granting themselves admin rights. This update introduces stricter access checks, actually enforcing the configured permissions and roles. This means that the configuration may need updating. In addition, user registration via the web interface has been disabled use the program roundup-admin from the command line instead. For the old stable distribution (etch), this problem has been fixed in version 1.2.1-10+etch1. For the stable distribution (lenny), this problem has been fixed in version 1.4.4-4+lenny1. We recommend that you upgrade your roundup package.
