    KDE Security Advisory: KGhostview Arbitary Code Execution
    Original Release Date: 2002-10-08
    URL: http://www.kde.org/info/security/advisory-20021008-1.txt

            BUGTRAQ:20020926 iDEFENSE Security Advisory 09.26.2002:
            Exploitable Buffer Overflow in gv
            http://marc.theaimsgroup.com/?l=bugtraq&m=103305615613319&w=2

    1. Systems affected:

            KGhostView of any KDE release between KDE 1.1 and KDE 3.0.3a

    2. Overview:
                
            KGhostview includes a DSC 3.0 parser from GSview, which is vulnerable
            to a buffer overflow while parsing a specially crafted .ps input
            file. It also contains code from gv 3.5.x which is vulnerable to another
            buffer overflow triggered by malformed postscript or Adobe pdf files.

    3. Impact:
            
            Viewing certain Postscript or PDF files can result in the execution of
            arbitary code placed in the file and as a result opens possibilities for
            any remote manipulation under the local user account.
       
    4. Solution:
            
            Apply the patch listed in section 5 to kdegraphics/kghostview, or update
            to KDE 3.0.4.

            kdegraphics-3.0.4 can be downloaded from

            http://download.kde.org/stable/3.0.4 :
