                Linux-Mandrake Security Update Advisory


Package name:           xpdf
Date:                   August 29th, 2000
Advisory ID:            MDKSA-2000:041

Affected versions:      6.0, 6.1, 7.0, 7.1

Problem Description:

There is a potential race condation when using tmpnam() and
fopen() in xpdf versions prior to 0.91. This exploit can be only
used as root to overwrite arbitrary files if a symlink is created
between the calls to tmpname() and fopen(). There is also a problem
with malicious URL-type links in PDF documents that contain quote
characters which could also potentially be used to execute
arbitrary commands. This is due to xpdf calling system() with a
netscape (or similar) command plus the URL. The 0.91 release of
xpdf fixes both of these potential problems. Although there are no
known exploits, users are encouraged to upgrade their system with
these updates.


Please verify these md5 checksums of the updates prior to
upgrading to ensure the integrity of the downloaded package. You
can do this by running the md5sum program on the downloaded package
by using “md5sum package.rpm”.

To upgrade automatically, use « MandrakeUpdate
».

If you want to upgrade manually, download the updated package
from one of our FTP server mirrors and uprade with “rpm -Uvh
package_name”.

You can download the updates directly from:

ftp://ftp.linux.tucows.com/pub/distributions/Mandrake/Mandrake/updates

ftp://ftp.free.fr/pub/Distributions_Linux/Mandrake/updates

Or try one of the other mirrors listed at:

http://www.linux-mandrake.com/en/ftp.php3.

Updated packages are available in the “updates/[ver]/RPMS/”
directory. For example, if you are looking for an updated RPM
package for Linux-Mandrake 7.1, look for it in “updates/7.1/RPMS/”.
Updated source RPMs are available as well, but you generally do not
need to download them.

Please be aware that sometimes it takes the mirrors a few hours
to update, so if you want an immediate upgrade, please use one of
the two above-listed mirrors.
