EulerOS 2.0 SP8 : samba (EulerOS-SA-2020-1179)

medium Nessus Plugin ID 134013

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 :

 - There is an issue in all samba 4.11.x versions before 4.11.5, all samba 4.10.x versions before 4.10.12 and all samba 4.9.x versions before 4.9.18, where the removal of the right to create or modify a subtree would not automatically be taken away on all domain controllers.(CVE-2019-14902)

 - All samba versions 4.9.x before 4.9.18, 4.10.x before 4.10.12 and 4.11.x before 4.11.5 have an issue where if it is set with 'log level = 3' (or above) then the string obtained from the client, after a failed character conversion, is printed. Such strings can be provided during the NTLMSSP authentication exchange. In the Samba AD DC in particular, this may cause a long-lived process(such as the RPC server) to terminate. (In the file server case, the most likely target, smbd, operates as process-per-client and so a crash there is harmless).(CVE-2019-14907)

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.

Solution

Update the affected samba packages.
