+
+=======
+Details
+=======
+
+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.
