The remote host is missing an update to xpdf announced via advisory DSA 931-1. infamous41md and Chris Evans discovered several heap based buffer overflows in xpdf, the Portable Document Format (PDF) suite, that can lead to a denial of service by crashing the application or possibly to the execution of arbitrary code. For the old stable distribution (woody) these problems have been fixed in version 1.00-3.8.

For the stable distribution (sarge) these problems have been fixed in version 3.00-13.4. For the unstable distribution (sid) these problems have been fixed in version 3.01-4. We recommend that you upgrade your xpdf package. https://secure1.securityspace.com/smysecure/catid.html?in=DSA%20931-1
