Description James Brost 2002-10-14 20:50:17 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 Galeon/1.2.6 (X11; Linux i686; U;) Gecko/20020916

Description of problem:
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.

Version-Release number of selected component (if applicable):

How reproducible:
Didn't try

Steps to Reproduce:
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.

Additional info:

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