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
