Mandrake Linux Security Update Advisory ________________________________________________________________________
Package name: samba Date: June 29th, 2001 Advisory ID: MDKSA-2001:062
Affected versions: 7.1, 7.2, 8.0, Corporate Server 1.0.1 ________________________________________________________________________
Problem Description:
Michal Zalewski has found a vulnerability in all versions of Samba prior to 2.0.10 where if a client sends an invalid netbios name Samba could be tricked into appending it's log to files writable by root. This can be very dangerous if combined with a symlink created by a local user. Note that the log files must be specified as %m.log in order for this to work, and Mandrake Linux ships Samba by default using log.%m, thus it is not vulnerable "out of the box". ________________________________________________________________________

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 Mandrake Linux Security Team at http://www.linux-mandrake.com/en/security/RPM-GPG-KEYS 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 upgrade with "rpm -Fvh *.rpm".
You can download the updates directly from one of the mirror sites 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 Mandrake Linux 8.0, look for it in "updates/8.0/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.
