(Red Hat Issues Fix) Xpdf Buffer Overflows in Processing DCT and JPX Streams May Let Remote Users Execute Arbitrary Code
SecurityTracker Alert ID:  1015388
SecurityTracker URL:  http://securitytracker.com/id/1015388
CVE Reference:   CVE-2005-3191, CVE-2005-3192   (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): 3.0.1
Description:   Several vulnerabilities were reported in Xpdf. A remote user may be able to cause arbitrary code to be executed on the target system.

The DCT stream parsing code does not properly validate user-supplied input. The DCTStream::readBaselineSOF() function in 'xpdf/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 'xpdf/JPXStream.cc' does not properly validate the 'nXTiles' and 'nYTiles' parameters.

The vendor was notified on October 13, 2005.

iDEFENSE reported these vulnerabilities.

http://www.idefense.com/application/poi/display?id=344&type=vulnerabilities
http://www.idefense.com/application/poi/display?id=345&type=vulnerabilities

Impact:   A remote user can create a specially crafted PDF file that, when processed by the target user, may be able to cause arbitrary code to be executed on the target system with the privileges of the target user.
Solution:   Red Hat has released a fix.

3. Problem description:

The xpdf package is an X Window System-based viewer for Portable Document
Format (PDF) files.

Several flaws were discovered in Xpdf.  An attacker could construct a
carefully crafted PDF file that could cause Xpdf 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 Xpdf should upgrade to this updated package, which contains a
backported patch to resolve these issues.

Red Hat would like to thank Derek B. Noonburg for reporting this issue and
providing a patch.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.  Use Red Hat
Network to download and update your packages.  To launch the Red Hat
Update Agent, use the following command:

    up2date

For information on how to install packages manually, refer to the
following Web page for the System Administration or Customization
guide specific to your system:
