NewStart CGSL MAIN 4.05 : samba4 Multiple Vulnerabilities (NS-SA-2019-0115)
High Nessus Plugin ID 127355
SynopsisThe remote machine is affected by multiple vulnerabilities.
DescriptionThe 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.
- 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.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
SolutionUpgrade the vulnerable CGSL samba4 packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
