The remote Debian host is missing a security-related 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.
Upgrade the samba packages. For the stable distribution (wheezy), these problems have been fixed in version 2:3.6.6-6+deb7u4.
