Description

Updated samba packages fix security vulnerabilities :

Information leak vulnerability in the VFS code, allowing an authenticated user to retrieve eight bytes of uninitialized memory when shadow copy is enabled (CVE-2014-0178).

Samba versions before 3.6.24, 4.0.19, and 4.1.9 are vulnerable to a denial of service on the nmbd NetBIOS name services daemon. A malformed packet can cause the nmbd server to loop the CPU and prevent any further NetBIOS name service (CVE-2014-0244).

Samba versions before 3.6.24, 4.0.19, and 4.1.9 are affected by a denial of service crash involving overwriting memory on an authenticated connection to the smbd file server (CVE-2014-3493).
