Juniper Junos OS Multiple Vulnerabilities (JSA71655)

high Nessus Plugin ID 178191

Language:

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

The version of Junos OS installed on the remote host is affected by multiple vulnerabilities as referenced in the JSA71655 advisory.

 - The Eclipse Mosquitto broker up to version 1.4.15 does not reject strings that are not valid UTF-8. A malicious client could cause other clients that do reject invalid UTF-8 strings to disconnect themselves from the broker by sending a topic string which is not valid UTF-8, and so cause a denial of service for the clients. (CVE-2017-7653)

 - In Eclipse Mosquitto 1.4.15 and earlier, a Memory Leak vulnerability was found within the Mosquitto Broker. Unauthenticated clients can send crafted CONNECT packets which could cause a denial of service in the Mosquitto Broker. (CVE-2017-7654)

 - In Eclipse Mosquitto version from 1.0 to 1.4.15, a Null Dereference vulnerability was found in the Mosquitto library which could lead to crashes for those applications using the library. (CVE-2017-7655)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
