                   Red Hat, Inc. Security Advisory

Synopsis:          xpdf bugfix release
Advisory ID:       RHSA-2000:060-03
Issue date:        2000-09-13
Updated on:        2000-09-13
Product:           Red Hat Linux
Keywords:          security problem in temporary file and malicious URL.
Cross references:  N/A
---------------------------------------------------------------------

1. Topic:

Security problem in temporary file and malicious URL.

2. Relevant releases/architectures:

Red Hat Linux 5.2 - i386, alpha, sparc
Red Hat Linux 6.2 - i386, alpha, sparc

3. Problem description:

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.
 
The xpdf-0.91 fixes both these security problems.

4. Solution:

For each RPM for your particular architecture, run:

rpm -Fvh [filename]

where filename is the name of the RPM.

5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):

N/A
