Linux-Mandrake: samba vulnerability

Author: JT Smith

From 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.
