HP Security Bulletin HPSBUX03574 1 - Potential security vulnerabilities have been identified with HP-UX CIFS-Server (Samba). The vulnerabilities could be exploited remotely to cause access restriction bypass, authentication bypass, Denial of Service (DoS), unauthorized access to files, access restriction bypass, or unauthorized information disclosure. Revision 1 of this advisory.
3425ca46ec9693308573785c2ac516d648f5b8e32172b2e8f2ba16ba7c8482b9Mandriva Linux Security Advisory 2015-082 - In Samba before 3.6.23, the SAMR server neglects to ensure that attempted password changes will update the bad password count, and does not set the lockout flags. This would allow a user unlimited attempts against the password by simply calling ChangePasswordUser2 repeatedly. This is available without any other authentication. Information leak vulnerability in the VFS code, allowing an authenticated user to retrieve eight bytes of uninitialized memory when shadow copy is enabled. 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 ame service. 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. An uninitialized pointer use flaw was found in the Samba daemon (smbd). A malicious Samba client could send specially crafted netlogon packets that, when processed by smbd, could potentially lead to arbitrary code execution with the privileges of the user running smbd (by default, the root user).

Versions less than 3.6.25 are affected.
606c956ce8f163cd743c45062fd6201fce247d72cbe7bc650aed2d2440e1861bRed Hat Security Advisory 2014-0383-01 - Samba is an open-source implementation of the Server Message Block or Common Internet File System protocol, which allows PC-compatible machines to share files, printers, and other information. 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. 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.

A remote attacker could use this issue to possibly attempt to brute force user passwords.

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. 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.
