    1. Systems affected:

            KOffice 1.3 up to including KOffice 1.3.5

    2. Overview:

            The KOffice PDF Import Filter shares code with xpdf. xpdf contains
            a buffer overflow that can be triggered by a specially crafted
            PDF file.

    3. Impact:

            Remotely supplied pdf files can be used to execute arbitrary
            code on the client machine when the user opens such file in
            KOffice.

    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 KOffice 1.3.5 is available from
            ftp://ftp.kde.org/pub/kde/security_patches :

            0e6194cbfe3f6d3b3c848c2c76ef5bfb post-1.3.5-koffice.diff

    6. Time line and credits:

            19/01/2005 KDE Security Team alerted by Carsten Lohrke
            19/01/2005 Patches from xpdf 3.00pl3 applied to KDE CVS and patches
                       prepared.
            20/01/2005 Public disclosure.
