Samba 4.0.x < 4.0.18 / 4.1.x < 4.1.8 Multiple Vulnerabilities

medium Nessus Network Monitor Plugin ID 3540
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote version of Samba is outdated and thus affected by several vulnerabilities.

Description

Versions of Samba older than 4.0.18 or 4.1.8 are unpatched for the following vulnerabilities:

- An error in the 'dns_process_send()' function in the internal DNS server can cause an infinite loop that results in denial of service, due to the server not checking the 'reply' flag in a DNS packet header when processing a request. (CVE-2014-0239)

- A flaw in the 'vfswrap_fsctl()' function that is triggered when responding to authenticated FSCTL_GET_SHADOW_COPY_DATA or FSCTL_SRV_ENUMERATE_SNAPSHOTS client requests can result in the exposure of eight bytes of uninitialized memory. This affects versions of Samba 3.6.6 and onward. (CVE-2014-0178)

Solution

Install the patch referenced in the project's advisory, or upgrade to 4.0.18, 4.1.8, or later.
