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.
