- Michal Zalewski discovered that Samba does not properly validate
- NetBIOS names from remote machines.
-
- By itself that is not a problem, except if Samba is configured to
- write log-files to a file that includes the NetBIOS name of the
- remote side by using the `%m\' macro in the `log file\' command. In
- that case an attacker could use a NetBIOS name like \'../tmp/evil\'.
- If the log-file was set to "/var/log/samba/%s" Samba would then
- write to /var/tmp/evil.
-
- Since the NetBIOS name is limited to 15 characters and the `log
- file\' command could have an extension to the filename the results
- of this are limited. However if the attacker is also able to create
- symbolic links on the Samba server they could trick Samba into
- appending any data they want to all files on the filesystem which
- Samba can write to.
-
- The Debian GNU/Linux packaged version of Samba has a safe
- configuration and is not vulnerable.
-
- As temporary workaround for systems that are vulnerable change all
- occurrences of the `%m\' macro in smb.conf to `%l\' and restart Samba.
-
- This has been fixed in version 2.0.7-3.4, and we recommend that you
- upgrade your Samba package immediately.
