More information:

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.
