Linux-Mandrake Security Update Advisory ________________________________________________________________________
Package name: samba Date: April 20th, 2001 Advisory ID: MDKSA-2001:040
Affected versions: 7.1, 7.2, 8.0, Corporate Server 1.0.1 ________________________________________________________________________
Problem Description:
A vulnerability found by Marcus Meissner exists in Samba where it was not creating temporary files safely which could allow local users to overwrite files that they may not have access to. This happens when a remote user queried a printer queue and samba would create a temporary file in which the queue's data was written. Because Samba created the file insecurely and used a predictable filename, a local attacker could cause Samba to overwrite files that the attacker did not have access to. As well, the smbclient "more" and "mput" commands also created temporary files insecurely.
The vulnerability is present in Samba 2.0.7 and lower. 2.0.8 and 2.2.0 correct this behaviour. ________________________________________________________________________
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 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 Linux-Mandrake 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.
