| Class |
Samba |
| Detailed Description |
The version of Samba running on the remote host is 3.6.x prior to 4.11.15, 4.12.x prior to 4.12.9, or 4.13.x prior to 4.13.1. It is, therefore, potentially affected by multiple vulnerabilities, including the following:
- 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)
- A missing permissions check on a directory handle can leak file name information to unprivileged accounts. (CVE-2020-14318)
- An error in Samba's dnsserver RPC pipe when no data is present in the DNS records additional section. An authenticated, non-admin user can exploit this to crash the DNS server by adding invalid records. (CVE-2020-14383)
