Package        : samba
Problem type   : local symlink attack
Debian-specific: no

Marc Jacobsen from HP discovered that the security fixes from samba
2.0.8 did not fully fix the /tmp symlink attack problem. The samba
team released version 2.0.9 to fix that, and those fixes have been
added to version 2.0.7-3.3 of the Debian samba packages.
