Descriptions

The modern style negotiation in Network Block Device (nbd-server) 2.9.22 through 3.3 allows remote attackers to cause a denial of service (root process termination) by (1) closing the connection during negotiation or (2) specifying a name for a non-existent export.

La negociación del estilo moderno en Network Block Device (nbd-server) 2.9.22 hasta 3.3 permite a atacantes remotos causar una denegación de servicio (terminación del proceso root) mediante (1) el cierre de la conexión durante la negociación o (2) la especificación de un nombre para una exportación no existente.

It was discovered that NBD incorrectly handled IP address matching. A remote attacker could use this issue with an IP address that has a partial match and bypass access restrictions. This issue only affected Ubuntu 12.04 LTS. Tuomas discovered that NBD incorrectly handled wrong export names and closed connections during negotiation.
