Yellow Dog Linux Security Announcement
--------------------------------------

Package:	xpdf
Issue Date:	Jul 23,2003   
Priority:	medium
Advisory ID: 	YDU-20030723-1


1. 	Topic:

	Updated xpdf packages are available.


2. 	Problem:

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

	Martyn Gilmore discovered a flaw in various PDF viewers and readers. An
	attacker can embed malicious external-type hyperlinks that, if activated or
	followed by a victim, can execute arbitrary shell commands. The Common
	Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
	CAN-2003-0434 to this issue.

	All users of Xpdf are advised to upgrade to these errata packages, which
	contain a backported security patch that corrects this issue."

	From Red Hat Advisory


3. 	Solution:

   	a) Updating via yum... 
	We suggest that you use the yum program to keep your
        system up-to-date. The following command(s) will retrieve
	and install the fixed version of this update onto your system:

		yum update xpdf

	b) Updating manually...
