   Samba 4.12.4
   ============
   o  CVE-2020-10730:
      A client combining the 'ASQ' and 'VLV' LDAP controls can cause a NULL pointer
      de-reference and further combinations with the LDAP paged_results feature can
      give a use-after-free in Samba's AD DC LDAP server.

   o  CVE-2020-10745: Parsing and packing of NBT and DNS packets can consume
      excessive CPU.

   o  CVE-2020-10760:
      The use of the paged_results or VLV controls against the Global Catalog LDAP
      server on the AD DC will cause a use-after-free.

   o  CVE-2020-14303:
      The AD DC NBT server in Samba 4.0 will enter a CPU spin and not process
      further requests once it receives an empty (zero-length) UDP packet to
      port 137.

   For more details, please refer to the security advisories.
