CVE-2014-0178

Status Candidate

Overview

Samba 3.6.6 through 3.6.23, 4.0.x before 4.0.18, and 4.1.x before 4.1.8, when a certain vfs shadow copy configuration is enabled, does not properly initialize the SRV_SNAPSHOT_ARRAY response field, which allows remote authenticated users to obtain potentially sensitive information from process memory via a (1) FSCTL_GET_SHADOW_COPY_DATA or (2) FSCTL_SRV_ENUMERATE_SNAPSHOTS request.

Mandriva Linux Security Advisory 2015-082
Posted Mar 30, 2015
Authored by Mandriva | Site mandriva.com

Mandriva 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).

Red Hat Security Advisory 2014-0867-01
Posted Jul 9, 2014

Red Hat Security Advisory 2014-0867-01 - 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. A denial of service flaw was found in the way the sys_recvfile() function of nmbd, the NetBIOS message block daemon, processed non-blocking sockets. An attacker could send a specially crafted packet that, when processed, would cause nmbd to enter an infinite loop and consume an excessive amount of CPU time. A flaw was found in the way Samba created responses for certain authenticated client requests when a shadow-copy VFS module was enabled. An attacker able to send an authenticated request could use this flaw to disclose limited portions of memory per each request.

Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 2257-1 - Christof Schmitt discovered that Samba incorrectly initialized a certain response field when vfs shadow copy was enabled. A remote authenticated attacker could use this issue to possibly obtain sensitive information. This issue only affected Ubuntu 13.10 and Ubuntu 14.04 LTS. It was discovered that the Samba internal DNS server incorrectly handled QR fields when processing incoming DNS messages. A remote attacker could use this issue to cause Samba to consume resources, resulting in a denial of service. This issue only affected Ubuntu 14.04 LTS. Various other issues were also addressed.
