Synopsis
The remote FreeBSD host is missing one or more security-related updates.Description
Samba team reports :[CVE-2016-2123] Authenticated users can supply malicious dnsRecord attributes on DNS objects and trigger a controlled memory corruption.
[CVE-2016-2125] Samba client code always requests a forwardable ticket when using Kerberos authentication. This means the target server, which must be in the current or trusted domain/realm, is given a valid general purpose Kerberos 'Ticket Granting Ticket' (TGT), which can be used to fully impersonate the authenticated user or service.
[CVE-2016-2126] A remote, authenticated, attacker can cause the winbindd process to crash using a legitimate Kerberos ticket due to incorrect handling of the PAC checksum. A local service with access to the winbindd privileged pipe can cause winbindd to cache elevated access permissions.
