The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has samba packages installed that are affected by multiple vulnerabilities:

  - 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)

  - A flaw was found in the way samba handled file and directory permissions. An authenticated user could use     this flaw to gain access to certain file and directory information which otherwise would be unavailable to     the attacker. (CVE-2020-14318)

  - A null pointer dereference flaw was found in samba's Winbind service in versions before 4.11.15, before     4.12.9 and before 4.13.1. A local user could use this flaw to crash the winbind service causing denial of     service. (CVE-2020-14323)

  - An elevation of privilege vulnerability exists when an attacker establishes a vulnerable Netlogon secure     channel connection to a domain controller, using the Netlogon Remote Protocol (MS-NRPC), aka 'Netlogon     Elevation of Privilege Vulnerability'. (CVE-2020-1472)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
