Description

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.
