                Linux-Mandrake Security Update Advisory

Package name:           kdesu
Date:                   January 31st, 2001
Advisory ID:            MDKSA-2001:018

Affected versions:      6.1, 7.0, 7.1, 7.2, Corporate Server 1.0.1

Problem Description:

A problem exists with the kdesu program for KDE versions 1 and 2. kdesu is a frontend for the su program, allowing normal users to run programs with root privileges by prompting for the root password. When the "keep password" option is enabled, kdesu tries to send the password across process boundaries to kdesud via a UNIX socket. During this, it does not verify the identity of the listener on the other end, which can allow attackers to obtain the root password.

As of Linux-Mandrake 7.2, the kdesu program is a part of the kdebase package, and libraries for kdesu are found in the kdelibs package.

Please verify the update prior to upgrading to ensure the integrity of the downloaded package. You can do this with the command:
rpm --checksig package.rpm
You can get the GPG public key of the Linux-Mandrake Security Team at

If you use MandrakeUpdate, the verification of md5 checksum and GPG signature is performed automatically for you.

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.
