1. Summary:

An updated xpdf package that fixes several security issues is 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
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64

3. Problem description:

Xpdf is an X Window System based viewer for Portable Document Format (PDF)
files.

A buffer overflow flaw was found in the Gfx::doImage function of 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 (cve.mitre.org) has assigned the name
CAN-2004-1125 to this issue.

A buffer overflow flaw was found in the Decrypt::makeFileKey2 function of
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 (cve.mitre.org) has assigned
the name CAN-2005-0064 to this issue.

During a source code audit, Chris Evans and others discovered a number of
integer overflow bugs that affected all versions of Xpdf. An attacker could
construct a carefully crafted PDF file that could cause Xpdf to crash or
possibly execute arbitrary code when opened. This issue was assigned the
name CAN-2004-0888 by The Common Vulnerabilities and Exposures project
(cve.mitre.org).  Red Hat Enterprise Linux 4 contained a fix for this
issue, but it was found to be incomplete and left 64-bit architectures
vulnerable.  The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2005-0206 to this issue.

All users of Xpdf should upgrade to this updated package, which contains
backported patches to 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:

5. Bug IDs fixed (http://bugzilla.redhat.com/):

135066 - PDF is displayed garbled, older xpdf works
144197 - CAN-2004-1125 xpdf buffer overflow
145052 - CAN-2005-0064 xpdf buffer overflow
