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
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:
Or try one of the other mirrors listed at:
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.
