high Nessus Plugin ID 76279

Language:

Synopsis

The remote host is affected by a denial of service vulnerability.

Description

The remote host is running a version of Juniper ScreenOS 6.3 prior to 6.3.0r17. It is, therefore, affected by a denial of service vulnerability.

A denial of service flaw exists in the built-in DNS lookup client. The flaw could allow a remote attacker to cause the device to crash or reboot, and repeated exploitation can result in an extended denial of service condition.

Solution

Upgrade to 6.3.0r17 or later.
