== Subject: Misconfigured /etc/passwd file may share folders unexpectedly
== CVE ID#: CVE-CVE-2009-2813
== Versions: All versions of Samba later than 3.0.11
== Summary: If a user in /etc/passwd is misconfigured to have
== an empty home directory then connecting to the home
== share of this user will use the root of the filesystem
== as the home directory.
If a user in /etc/passwd is misconfigured to have an empty home
directory (::) and the automated [homes] share is enabled, or an
explicit share is created with that username, then any client connecting
to that share name will be able to access the whole filesystem from
root (/) on downwards, subject to local file system permissions
applied to the connecting user.
Patches addressing both these issues have been posted to:
(Karolin: can you fill in this part?)
Do not configure users in /etc/passwd with a blank home
