(Red Hat Issues Fix) Xpdf Buffer Overflow in makeFileKey2() Lets Remote Users Execute Arbitrary Code
SecurityTracker Alert ID:  1013062
SecurityTracker URL:  http://securitytracker.com/id/1013062
CVE Reference:   CVE-2005-0064   (Links to External Site)
Date:  Feb 2 2005
Impact:   Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): prior to 3.00pl3
Description:   iDEFENSE reported a buffer overflow vulnerability in Xpdf. A remote user may be able to execute arbitrary code on the target system.

A remote user can create a specially crafted PDF file to trigger a stack overflow in the 'Decrypt::makeFileKey2' function in the processing of the /Encrypt /Length tag. Arbitrary code can be executed with the privileges of the Xpdf process or the user running Xpdf.

The flaw resides in 'xpdf/Decrypt.cc'.

The vendor was notified on January 6, 2005.

The original advisory is available at:

http://www.idefense.com/application/poi/display?id=186&type=vulnerabilities

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

                   Red Hat Security Advisory

Synopsis:          Updated CUPS packages fix security issue
Advisory ID:       RHSA-2005:049-01
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2005-049.html
Issue date:        2005-02-01
Updated on:        2005-02-01
Product:           Red Hat Enterprise Linux
CVE Names:         CAN-2005-0064
- ---------------------------------------------------------------------

1. Summary:

Updated CUPS packages that fixes a security issue are now available.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, ppc64, s390, s390x, x86_64
Red Hat Desktop version 3 - i386, x86_64
Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64

3. Problem description:

The Common UNIX Printing System provides a portable printing layer for
UNIX(R) operating systems.

A buffer overflow flaw was found in the Decrypt::makeFileKey2 function of
Xpdf which also affects the CUPS pdftops filter due to a shared codebase.
An attacker who has the ability to send a malicious PDF file to a printer
could possibly execute arbitrary code as the "lp" user. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2005-0064 to this issue.

Red Hat believes that the Exec-Shield technology (enabled by default since
Update 3) will block attempts to remotely exploit these buffer overflow
vulnerabilities on x86 architectures.

All users of cups should upgrade to these updated packages, which resolve
these issues.

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:

    http://www.redhat.com/docs/manuals/enterprise/
