SUSE SLES12 Security Update : samba (SUSE-SU-2020:2721-1)

critical Nessus Plugin ID 143864

Language:

Synopsis

The remote SUSE host is missing one or more security updates.

Description

This update for samba fixes the following issues :

ZeroLogon: An elevation of privilege was possible with some configurations when an attacker established a vulnerable Netlogon secure channel connection to a domain controller, using the Netlogon Remote Protocol (MS-NRPC) (CVE-2020-1472, bsc#1176579).

Fixed an issue where multiple home folders were created(bsc#1174316, bso#13369).

Fixed an issue where the net command was unable to negotiate SMB2 (bsc#1174120);

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
