Descriptions

The samldb_check_user_account_control_acl function in dsdb/samdb/ldb_modules/samldb.c in Samba 4.x before 4.1.22, 4.2.x before 4.2.7, and 4.3.x before 4.3.3 does not properly check for administrative privileges during creation of machine accounts, which allows remote authenticated users to bypass intended access restrictions by leveraging the existence of a domain with both a Samba DC and a Windows DC, a similar issue to CVE-2015-2535.

La función samldb_check_user_account_control_acl en dsdb/samdb/ldb_modules/samldb.c en Samba 4.x en versiones anteriores a 4.1.22, 4.2.x en versiones anteriores a 4.2.7 y 4.3.x en versiones anteriores a 4.3.3 no comprueba adecuadamente los privilegios administrativos durante la creación de cuentas de máquina, lo que permite a usuarios remotos autenticados eludir las restricciones de acceso destinadas aprovechando la existencia de un dominio tanto con un Samba DC como con un Windows DC, un caso similar a CVE-2015-2535

Thilo Uttendorfer discovered that the Samba LDAP server incorrectly handled certain packets. A remote attacker could use this issue to cause the LDAP server to stop responding, resulting in a denial of service. This issue only affected Ubuntu 14.04 LTS, Ubuntu 15.04 and Ubuntu 15.10. Jan Kasprzak discovered that Samba incorrectly handled certain symlinks. A remote attacker could use this issue to access files outside the exported share path. Various other issues were also addressed.
