Synopsis: Moderate: samba4 security update
Advisory ID: SLSA-2014:0383-1
Issue Date: 2014-04-09
CVE Numbers: CVE-2012-6150
 CVE-2013-4496
 CVE-2013-6442
--

It was found that certain Samba configurations did not enforce the
password lockout mechanism. A remote attacker could use this flaw to
perform password guessing attacks on Samba user accounts. Note: this flaw
only affected Samba when deployed as a Primary Domain Controller.
(CVE-2013-4496)

A flaw was found in Samba's "smbcacls" command, which is used to set or
get ACLs on SMB file shares. Certain command line options of this command
would incorrectly remove an ACL previously applied on a file or a
directory, leaving the file or directory without the intended ACL.
(CVE-2013-6442)

A flaw was found in the way the pam_winbind module handled configurations
that specified a non-existent group as required. An authenticated user
could possibly use this flaw to gain access to a service using pam_winbind
in its PAM configuration when group restriction was intended for access to
the service. (CVE-2012-6150)

After installing this update, the smb service will be restarted
automatically.
