----------------------------------------------------------------------

1. Summary:

Updated Xpdf package that fixes a stack based buffer overflow security issue is now available.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Desktop version 3 - i386, x86_64
Red Hat Enterprise Linux ES version 3 - 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 when processing the /Encrypt /Length tag. 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.

Red Hat believes that the Exec-Shield technology (enabled by default since Update 3) will block attempts to exploit this vulnerability on x86 architectures.

All users of the Xpdf package should upgrade to this updated package, which resolves this issue

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:
