Samba 4.x < 4.0.18 Multiple Vulnerabilities
Low Nessus Plugin ID 74242
SynopsisThe remote Samba server is potentially affected by multiple vulnerabilities.
DescriptionAccording 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.
SolutionEither 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.
