Samba 3.5.x / 3.6.x < 3.6.25 / 4.1.x < 4.1.8 Multiple Vulnerabilities

low Nessus Plugin ID 74290
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 Samba server is potentially affected by multiple vulnerabilities.

Description

According to its banner, the version of Samba running on the remote host is 3.5.x or 3.6.x prior to 3.6.25 / 4.1.x prior to 4.1.8. It is, therefore, potentially affected by the following vulnerabilities :

- An error exists related to GET_SHADOW_COPY_DATA() and FSCTL_SRV_ENUMERATE_SNAPSHOTS() request handling in which the SRV_SNAPSHOT_ARRAY response field is not properly initialized. Therefore, configurations with 'shadow_copy' or 'shadow-copy2' specified for the 'vfs objects' parameter can allow the disclosure of uninitialized memory contents. (CVE-2014-0178)

- A denial of service vulnerability exists due to the internal DNS server failing to check the 'reply' flag in DNS packet headers. A remote attacker, via a forged response packet that triggers a communication loop, can cause the consumption of CPU processing and bandwidth.
(CVE-2014-0239)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Samba 3.6.25 / 4.1.8 or later. Alternatively, install the patch or apply the workaround referenced in the vendor advisory.
