NewStart CGSL MAIN 4.05 : samba4 Multiple Vulnerabilities (NS-SA-2019-0115)

critical Nessus Plugin ID 127355

Language:

Synopsis

The remote machine is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version MAIN 4.05, has samba4 packages installed that are affected by multiple vulnerabilities:

 - An information leak flaw was found in the way SMB1 protocol was implemented by Samba. A malicious client could use this flaw to dump server memory contents to a file on the samba share or to a shared printer, though the exact area of server memory cannot be controlled by the attacker. (CVE-2017-12163)

 - It was found that samba did not enforce SMB signing when certain configuration options were enabled. A remote attacker could launch a man-in-the-middle attack and retrieve information in plain-text. (CVE-2017-12150)

 - A memory disclosure flaw was found in samba. An attacker could retrieve parts of server memory, which could contain potentially sensitive data, by sending specially-crafted requests to the samba server.
 (CVE-2017-15275)

 - A use-after-free flaw was found in the way samba servers handled certain SMB1 requests. An unauthenticated attacker could send specially-crafted SMB1 requests to cause the server to crash or execute arbitrary code.
 (CVE-2017-14746)

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

Solution

Upgrade the vulnerable CGSL samba4 packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
