The remote host is missing an update to koffice announced via advisory DSA 938-1. infamous41md and chris Evans discovered several heap based buffer overflows in xpdf, the Portable Document Format (PDF) suite, which is also present in koffice, the KDE Office Suite, and which can lead to a denial of service by crashing the application or possibly to the execution of arbitrary code. The old stable distribution (woody) does not contain koffice packages.

For the stable distribution (sarge) these problems have been fixed in version 1.3.5-4.sarge.2. For the unstable distribution (sid) these problems have been fixed in version 1.4.2-6. We recommend that you upgrade your koffice package. https://secure1.securityspace.com/smysecure/catid.html?in=DSA%20938-1
