Descriptions
The LDAP server in the AD domain controller in Samba 4.x before 4.1.22 does not check return values to ensure successful ASN.1 memory allocation, which allows remote attackers to cause a denial of service (memory consumption and daemon crash) via crafted packets.
El servidor LDAP en el controlador de dominio AD en Samba 4.x en versiones anteriores a 4.1.22 no comprueba los valores de retorno para asegurar que la asignación de memoria ASN.1 tuvo éxito, lo que permite a atacantes remotos provocar una denegación de servicio (consumo de memoria y caída de demonio) a través de paquetes manipulados.
A denial of service flaw was found in the LDAP server provided by the AD DC in the Samba process daemon. A remote attacker could exploit this flaw by sending a specially crafted packet, which could cause the server to consume an excessive amount of memory and crash.
