    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 :
