Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Credentials management (CVE-ID: CVE-2013-4496)

The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

Samba 3.x before 3.6.23, 4.0.x before 4.0.16, and 4.1.x before 4.1.6 does not enforce the password-guessing protection mechanism for all interfaces, which makes it easier for remote attackers to obtain access via brute-force ChangePasswordUser2 (1) SAMR or (2) RAP attempts.


2) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2013-6442)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

The owner_set function in smbcacls.c in smbcacls in Samba 4.0.x before 4.0.16 and 4.1.x before 4.1.6 removes an ACL during use of a --chown or --chgrp option, which allows remote attackers to bypass intended access restrictions in opportunistic circumstances by leveraging an unintended administrative change.


Remediation

Install update from vendor's website.
