The remote host is missing an update to gpdf announced via advisory DSA 974-1. SuSE researchers discovered heap overflow errors in xpdf, the Portable Document Format (PDF) suite, which is also present in gpdf, the GNOME version of the Portable Document Format viewer, and which can allow attackers to cause a denial of service by crashing the application or possibly execute arbitrary code. The old stable distribution (woody) does not contain gpdf packages.

For the stable distribution (sarge) these problems have been fixed in version 2.8.2-1.2sarge3. For the unstable distribution (sid) these problems will be fixed soon. We recommend that you upgrade your gpdf package. https://secure1.securityspace.com/smysecure/catid.html?in=DSA%20974-1
