1. Systems affected:

2. Overview:

        kpdf, the KDE pdf viewer, shares code with xpdf. xpdf contains
        a heap based buffer overflow in the splash rasterizer engine
        that can crash kpdf or even execute arbitrary code.


3. Impact:

	code on the client machine.


4. Solution:

        Source code patches have been made available which fix these
        vulnerabilities. Contact your OS vendor / binary package provider
        for information about how to obtain updated binary packages.


5. Patch:

        Patch for KDE 3.4.3 is available from
