Descriptions
slapd in OpenLDAP before 2.4.30 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via an LDAP search query with attrsOnly set to true, which causes empty attributes to be returned.
slapd de OpenLDAP anteriores a 2.4.30 permite a atacantes remotos provocar una denegación de servicio (fallo de aserción y finalización del demonio) a través de una petición de búsqueda LDAP con attrsOnly asignado a "true", lo que provoca que atributos vacíos sean devueltos.
It was discovered that OpenLDAP incorrectly handled certain search queries that returned empty attributes. A remote attacker could use this issue to cause OpenLDAP to assert, resulting in a denial of service. This issue only affected Ubuntu 12.04 LTS. Michael Vishchers discovered that OpenLDAP improperly counted references when the rwm overlay was used. A remote attacker could use this issue to cause OpenLDAP to crash, resulting in a denial of service. Various other issues were also addressed.
