Low Nessus Plugin ID 74242

New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 3.4

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 4.x prior to 4.0.18 and is, therefore, potentially affected by the following vulnerabilities :

- An error exists related to 'GET_SHADOW_COPY_DATA' or 'FSCTL_SRV_ENUMERATE_SNAPSHOTS' request handling and 'vfs objects' parameter configurations of 'shadow_copy' or 'shadow_copy2' that could allow disclosure of uninitialized memory contents. (CVE-2014-0178)

- An error exists related to handling the 'reply' flag DNS packet headers that could allow denial of service attacks. (CVE-2014-0239)

Note that Nessus has relied only on the self-reported version number and has not actually tried to exploit these issues or determine if the associated patch has been applied.

Solution

Either install the patch referenced in the project's advisory, or upgrade to 4.0.18 or later.

Alternatively, refer to the vendor advisories and apply the suggested workarounds.
