Details

Björn Baumbach discovered that Samba incorrectly validated permissions when
changing account passwords via LDAP. An authenticated attacker could use this
issue to change the password of other users, including administrators, and
perform actions as those users. (CVE-2018-1057)

It was discovered that Samba incorrectly validated inputs to the RPC spoolss
service. An authenticated attacker could use this issue to cause the service to
crash, resulting in a denial of service. (CVE-2018-1050)
