(Red Hat Issues Fix) KDE KOffice kpdf Buffer Overflows in Processing DCT and JPX Streams May Let Remote Users Execute Arbitrary Code
SecurityTracker Alert ID:  1015387
SecurityTracker URL:  http://securitytracker.com/id/1015387
CVE Reference:   CVE-2005-3191, CVE-2005-3192, CVE-2005-3193, CVE-2005-3624, CVE-2005-3625, CVE-2005-3626, CVE-2005-3627, CVE-2006-0746   (Links to External Site)
Date:  Dec 20 2005
Impact:   Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): KOffice 1.3.0 up to including KOffice 1.4.2
Description:   Several vulnerabilities were reported in KDE KOffice in the kpdf component. A remote user can cause arbitrary code to be executed on the target user's system.

The DCT stream parsing code does not properly validate user-supplied input. The DCTStream::readBaselineSOF() function in 'Stream.cc' does not properly validate the 'numComps' parameter. A remote user can create a specially crafted PDF file that, when processed by the target user, will trigger an overflow at potentially execute arbitrary code.

The DCTStream::readProgressiveSOF() and StreamPredictor::StreamPredictor() functions are also affected.

A similar overflow exists in the JPX Stream parsing code used in decoding embedded JPEG 2000 images. The JPXStream::readCodestream() function in 'JPXStream.cc' does not properly validate the 'nXTiles' and 'nYTiles' parameters.

The vulnerability resides in xpdf code that is shared with kpdf. The vulnerabilities in xpdf were originally reported by iDEFENSE.

In January 2006, the vendor issued an update to the advisory indicating that the original patches were incomplete and have been retracted.

In March 2006, it was reported that the fix for CVE-2005-3627 was not complete. The resulting vulnerability was assigned CVE-2006-0746. Marcelo Ricardo Leitner discovered this vulnerability.

Impact:   A remote user can create a PDF file that, when processed by the target user, will execute arbitrary code on the target user's system with the privileges of the target user.
Solution:   Red Hat has released a fix.

1. Summary:

Updated kdegraphics packages that resolve several security issues in kpdf
are now available.

This update has been rated as having important security impact by the Red
Hat Security Response Team.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64

The kdegraphics packages contain applications for the K Desktop Environment
including kpdf, a pdf file viewer.

Several flaws were discovered in kpdf. An attacker could construct a
carefully crafted PDF file that could cause kpdf to crash or possibly
execute arbitrary code when opened. The Common Vulnerabilities and
Exposures project assigned the names CVE-2005-3191, CVE-2005-3192, and
CVE-2005-3193 to these issues.

Users of kpdf should upgrade to these updated packages, which contain a
backported patch to resolve these issues.

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

This update is available via Red Hat Network.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
