EulerOS 2.0 SP2 : samba (EulerOS-SA-2017-1234)
high Nessus Plugin ID 103736
Synopsis
The remote EulerOS host is missing multiple security updates.Description
According to the versions of the samba packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :- 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 flaw was found in the way samba client used encryption with the max protocol set as SMB3. The connection could lose the requirement for signing and encrypting to any DFS redirects, allowing an attacker to read or alter the contents of the connection via a man-in-the-middle attack. (CVE-2017-12151)
- 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)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
