The remote host is missing an update to libextractor announced via advisory DSA 998-1. Derek Noonburg has fixed several potential vulnerabilities in xpdf, which are also present in libextractor, a library to extract arbitrary meta-data from files. The old stable distribution (woody) does not contain libextractor packages.

For the stable distribution (sarge) these problems have been fixed in version 0.4.2-2sarge3. For the unstable distribution (sarge) these problems have been fixed in version 0.5.10-1. We recommend that you upgrade your libextractor package. https://secure1.securityspace.com/smysecure/catid.html?in=DSA%20998-1
