KDE Security Advisory: KGhostview Arbitary Code Execution

by Nikola Strahija on October 12th, 2002 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 :

6065219c825102c843ba582c4a520cac kdegraphics-3.0.4.tar.bz2

5. Patch:

A patch for KDE 3.0.3 is available from :
9e33962406ac123e4fbdab20b4123ccf post-3.0.3-kdegraphics-kghostview.diff

A patch for KDE 2.2.2 is available from :
62a1178c6a1730cbab98bbc825adafe9 post-2.2.2-kdegraphics-kghostview.diff
Version: GnuPG v1.0.7 (GNU/Linux)
