In addition, ypbind may suffer from buffer overflows. In the ypserv program, a buffer overflow and format bug exist if the build system does not have vsyslog() or if configure fails to detect it. Both vulnerabilities were discovered by Olaf Kirch . ________________________________________________________________________ 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".

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.
