EulerOS 2.0 SP3 : samba (EulerOS-SA-2019-2018)

medium Nessus Plugin ID 129211

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 :

 - Samba 4.9.x before 4.9.9 and 4.10.x before 4.10.5 has a NULL pointer dereference, leading to Denial of Service.
 This is related to the AD DC DNS management server (dnsserver) RPC server process.(CVE-2019-12435)

 - A flaw was found in the way samba implemented an RPC endpoint emulating the Windows registry service API. An unprivileged attacker could use this flaw to create a new registry hive file anywhere they have unix permissions which could lead to creation of a new file in the Samba share.(CVE-2019-3880)

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.
