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.

Samba is an implementation of the SMB/CIFS protocol for Unix systems, providing support for cross-platform file and printer sharing with Microsoft Windows, OS X, and other Unix systems. Samba can also function as an NT4-style domain controller, and can integrate with both NT4 domains and Active Directory realms as a member server.
