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