The remote host is missing an update to koffice announced via advisory DSA 872-1. Chris Evans discovered a buffer overflow in the RTF importer of kword, a word processor for the KDE Office Suite that can lead to the execution of arbitrary code. The old stable distribution (woody) does not contain a kword package.

For the stable distribution (sarge) this problem has been fixed in version 1.3.5-4.sarge.1. For the unstable distribution (sid) this problem has been fixed in version 1.3.5-5. We recommend that you upgrade your kword package. https://secure1.securityspace.com/smysecure/catid.html?in=DSA%20872-1
