Package: smbfs
Version: 3.0.14a-1
Severity: serious
Justification: break security on upgrade

Hello Debian samba maintainers,

smbmount does not honour the uid and gid option with the sarge 2.4
kernel when the server has 'unix extensions' enabled.

The security problem is that 'unix extension' are not enabled with woody samba
server but are enabled by the upgrade to sarge (since this is the
default). At this point the bug in smbmount on the samba client allow
users on the client to access the samba share with the same permission
they would have on the server disregarding the uid/gid option passed to

Imagine a large red swirl here.
