Product : Fedora Core 3
Name : xpdf
Version : 3.01
Release : 0.FC3.4
Summary : A PDF file viewer for the X Window System.
Description :
Xpdf is an X Window System based viewer for Portable Document Format
(PDF) files. Xpdf is a small and efficient program which uses
standard X fonts.

---------------------------------------------------------------------
Update Information:

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
name CAN-2005-3193 to these issues.

Users of xpdf should upgrade to this updated package, which
contains a patch to resolve these issues.
