Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

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.

Solution

Update the affected packages.
