Linux-Mandrake Security Update Advisory
________________________________________________________________________
Package name: glibc
Date: August 29th, 2000
Advisory ID: MDKSA-2000:040
Affected versions: 7.0, 7.1
________________________________________________________________________
Problem Description:
A bug was discovered in ld.so that could allow local users to obtain
root privileges. The dynamic loader, ld.so, is responsible for
making shared libraries available within a program at run-time.
Normally, a user is allowed to load additional shared libraries when
executing a program; they can be specified with environment
variables such as LD_PRELOAD. Because this is not acceptable for
applications that are setuid root, ld.so normally removes these
environment variables for setuid root programs. The discovered bug
causes these environment variables to not be removed under certain
circumstances. While setuid programs themselves are not vulnerable,
external programs they execute can be affected by this problem.
These updated packages contain a patch from Caldera Systems,
Inc. that fixes this vulernability. It should be noted that as of
yet there are no known exploits for this problem, but all users
should update to these glibc
packages.
________________________________________________________________________
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.
