Yellow Dog Linux Security Announcement
--------------------------------------
Package: xpdf
Issue Date: September 26, 2000
Update Date: September 26, 2000
Priority: high
Advisory ID: YDU-20000926-2
1. Topic:
Security problem in temporary file and malicious URL.
2. Problem:
"There is a security problem when using tmpnam() and fopen(). in
versions prior to 0.91. The problem is seen when a root user overwrites
files where a symlink is created between the calls to tmpname() and
fopen().
There is also a problem with URL-type links in PDF documents that contain
quote characters which could also be used to execute arbitrary commands."
(from Red Hat advisory)
3. Solution:

We suggest that you use the Yellow Dog Update Program (yup)
