Details

Steven French discovered that Samba incorrectly handled ChangeNotify
permissions. A remote attacker could possibly use this issue to obtain file
name information. (CVE-2020-14318)

Bas Alberts discovered that Samba incorrectly handled certain winbind
requests. A remote attacker could possibly use this issue to cause winbind
to crash, resulting in a denial of service. (CVE-2020-14323)

Francis Brosnan Blázquez discovered that Samba incorrectly handled certain
invalid DNS records. A remote attacker could possibly use this issue to
cause the DNS server to crash, resulting in a denial of service.
(CVE-2020-14383)

Peter Eriksson discovered that Samba incorrectly handled certain negative
idmap cache entries. This issue could result in certain users gaining
unauthorized access to files, contrary to expected behaviour.
(CVE-2021-20254)
