Updated samba packages fix security vulnerabilities:
Malicious servers can cause Samba client code to return filenames containing path separators to calling code (CVE-2019-10218).
When the password contains multi-byte (non-ASCII) characters, the check password script does not receive the full password string (CVE-2019-14833).
Users with the "get changes" extended access right can crash the AD DC LDAP server by requesting an attribute using the range= syntax (CVE-2019-14847).
An authenticated user can crash the DCE/RPC DNS management server by creating records with matching the zone name (CVE-2019-14861).
The DelegationNotAllowed Kerberos feature restriction was not being applied when processing protocol transition requests (S4U2Self), in the AD DC KDC (CVE-2019-14870).
