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.
