smbd in Samba 3.3.11, 3.4.6, and 3.5.0, when libcap support is enabled, runs with the CAP_DAC_OVERRIDE capability, which allows remote authenticated users to bypass intended file permissions via standard filesystem operations with any client.

=net-fs/samba-3.4.9 is fixed and currently the only stable version in the tree. I rate this a B4, so it requires a vote.
