Details

Orange Tsai discovered that the Samba vfs_fruit module incorrectly handled
certain memory operations. A remote attacker could use this issue to cause
Samba to crash, resulting in a denial of service, or possibly execute
arbitrary code as root. (CVE-2021-44142)

Michael Hanselmann discovered that Samba incorrectly created directories.
In certain configurations, a remote attacker could possibly create a
directory on the server outside of the shared directory. (CVE-2021-43566)

Kees van Vloten discovered that Samba incorrectly handled certain aliased
SPN checks. A remote attacker could possibly use this issue to impersonate
services. (CVE-2022-0336)
