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
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
