いずれも、

   o CVE-2009-2813:
     In all versions of Samba later than 3.0.11, connecting to the home
     share of a user will use the root of the filesystem
     as the home directory if this user is misconfigured to have
     an empty home directory in /etc/passwd.

   o CVE-2009-2948:
     If mount.cifs is installed as a setuid program, a user can pass it a
     credential or password path to which he or she does not have access and
     then use the --verbose option to view the first line of that file.
     All known Samba versions are affected.

   o CVE-2009-2906:
     Specially crafted SMB requests on authenticated SMB connections can
     send smbd into a 100% CPU loop, causing a DoS on the Samba server.

への対応のようですが、CVE-2009-2813以外は参照すべきCVEのエントリが未だ
ないみたいなんですよねぇ...。
