samba - security update

Multiple vulnerabilities were discovered and fixed in Samba, a SMB/CIFS
file, print, and login server:

• CVE-2014-0178
  Information leak vulnerability in the VFS code, allowing an
  authenticated user to retrieve eight bytes of uninitialized memory
  when shadow copy is enabled.
• CVE-2014-0244
  Denial of service (infinite CPU loop) in the nmbd Netbios name
  service daemon. A malformed packet can cause the nmbd server to
  enter an infinite loop, preventing it to process later requests to
  the Netbios name service.
• CVE-2014-3493
  Denial of service (daemon crash) in the smbd file server daemon. An
  authenticated user attempting to read a Unicode path using a
  non-Unicode request can force the daemon to overwrite memory at an
  invalid address.

For the stable distribution (wheezy), these problems have been fixed in
version 2:3.6.6-6+deb7u4.

For the testing distribution (jessie), these problems have been fixed in
version 2:4.1.9+dfsg-1.

For the unstable distribution (sid), these problems have been fixed in
version 2:4.1.9+dfsg-1.

We recommend that you upgrade your samba packages.
