SuSE researchers discovered heap overflow errors in xpdf, the Portable Document Format (PDF) suite, which is also present in pdfkit.framework, the GNUstep framework for rendering PDF content, 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 pdfkit.framework packages.
For the stable distribution (sarge) these problems have been fixed in version 0.8-2sarge2.
For the unstable distribution (sid) these problems have been fixed in version 0.8-4 by switching to poppler.
We recommend that you upgrade your pdfkit.framework package.
