The remote host is missing an update to roundup announced via advisory DSA 1554-2.

https://secure1.securityspace.com/smysecure/catid.html?in=DSA%201554-2

Roundup, an issue tracking system, fails to properly escape HTML input, allowing an attacker to inject client-side code (typically JavaScript) into a document that may be viewed in the victim's browser. For the stable distribution (etch), this problem has been fixed in version 1.2.1-5+etch2. For the unstable distribution (sid), this problem has been fixed in version 1.3.3-3.1. We recommend that you upgrade your roundup packages.
