Descriptions

An issue was discovered in OpenAFS before 1.6.23 and 1.8.x before 1.8.2. Several data types used as RPC input variables were implemented as unbounded array types, limited only by the inherent 32-bit length field to 4 GB. An unauthenticated attacker could send, or claim to send, large input values and consume server resources waiting for those inputs, denying service to other valid connections.

Se ha descubierto un problema en OpenAFS, en versiones anteriores a la 1.6.23 y versiones 1.8.x anteriores a la 1.8.2. Se implementaron varios tipos de datos empleados como variables de entrada RPC como tipos de array sin limitar, limitados solo por el campo length de 32 bits a 4 GB. Un atacante no autenticado podría enviar o decir que envía valores de entrada grandes y consumir recursos del servidor mientras esperan por esas entradas, denegando el servicio a otras conexiones válidas.
