Nom du paquet: samba
Date: 2001-05-21
Advisory ID: MDKSA-2001:040-1
Affected versions: 8.0 i586 , 7.2 i586 , 7.1 i586 , CS1.0 i586

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. Update: The Samba 2.0.8 release did not entirely fix the temporary file issues in previous versions. The Samba team released 2.0.9 recently which does fix these problems completely. As well, the 8.0 packages will now not attempt to use /root/tmp as the temporary directory, but /var/tmp.
